WASHINGTON, D.C. – As of March 2026, the rubidium fountain clocks have met the benchmark of 15 years of continuous operation as part of the U.S. Naval Observatory’s Master Clock ensemble. Developed and built at the observatory, these clocks were originally brought online in 2011, and their integration as part of the Master Clock shortly after enabled the generation of a time-scale more precise than any other in the world, a standard that continues to be the case today.

Texas Doctor Convicted for Illegally Distributing More than a Million Pills

A federal jury in the Southern District of Texas convicted a Texas physician yesterday for unlawfully distributing more than a million pills of opioids and other dangerous controlled substances.

“Medical physicians who exploit their prescribing authority for profit over patient care break an inherent trust with their patients and we will hold them accountable,” said Assistant Attorney General Colin M. McDonald of the Justice Department’s National Fraud Enforcement Division. “The Department of Justice remains committed to protecting the public from dangerous and unlawful distribution of controlled substances, especially when the drug dealer is a doctor.”

“Patients put their trust and their lives into the hands of our medical and health care professionals,” said DEA Assistant Administrator Cheri Oz. “The highly addictive, dangerous misused drugs in this case – oxycodone and hydrocodone – are meant to treat pain, not cause it. DEA remains relentless in our pursuit of those who poison our communities and exploit our health care system, all to line their own pockets with the profit from other’s pain.”

According to court documents and evidence presented at trial, Barbara Marino, M.D., 65, of Tomball, was the sole prescribing physician at Angels Clinica. From Angels Clinica, Marino prescribed the highly dangerous, addictive, and commonly abused opioids oxycodone and hydrocodone and the muscle relaxer carisoprodol. Marino prescribed these drugs from a clinic hiding in plain sight, behind mirrored windows, in a Houston strip mall:

Many of the patients who received prescriptions from Marino were brought to Angels Clinica by street-level drug dealers, often called “crew leaders” or “runners.” These crew leaders and runners brought patients to Marino for prescriptions, filled those prescriptions at Houston-area pharmacies, and then sold the pills on the street. Angels Clinica was a cash-only clinic, charging people based on what drug Marino would prescribe them. In less than a year, Marino received more than $400,000 from Angels Clinica’s owners for writing prescriptions that lacked a legitimate medical purpose and were outside the usual course of professional medical practice.

Marino’s prescribing exhibited many of the red flags of a pill mill, as published in the Texas State Board of Pharmacies “YOU MIGHT BE A PILL MILL IF…” checklist. The evidence at trial showed that Marino intentionally disregarded all the red flags and prescribed almost every patient she saw the dangerous combination of an opioid, like oxycodone or hydrocodone, and the muscle relaxer carisoprodol. More than 99% of the time, Marino prescribed only the strongest short-acting versions of oxycodone, hydrocodone, and carisoprodol.

Among Marino’s patients was a woman in her third trimester of pregnancy.  Marino prescribed this pregnant patient the dangerous drug cocktail of hydrocodone and carisoprodol. The patient’s OB/GYN testified at trial about how dangerous that drug cocktail was for both the woman and her unborn child, and that the patient missed an important follow-up visit with the OB/GYN. As the prosecutor said in her closing arguments, this patient “didn’t go to her doctor, she went to her drug dealer.”

Another of Dr. Marino’s patients was a man who had been diagnosed as bipolar and schizophrenic.  The patient’s mother testified that he often claimed to be former President Richard Nixon.  Nonetheless, Dr. Marino prescribed him the hydrocodone and soma cocktail at least three times.

The jury convicted Marino of one count of conspiracy to distribute a controlled substance and four counts of distributing a controlled substance. Marino faces a maximum of 20 years in prison for each count. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

DEA investigated the case.

Trial Attorneys Drew Pennebaker and Yael Mash of the Criminal Division’s Fraud Section and the Texas Attorney General’s Office Medicaid Fraud Control Unit are prosecuting the case.

On April 7, the Department of Justice announced the creation of the National Fraud Enforcement Division (“Fraud Division”). The Fraud Division is laser-focused on investigating and prosecuting those who commit fraud against the American people. The Department’s work to combat fraud supports President Trump’s Task Force to Eliminate Fraud, a whole-of-government effort chaired by Vice President J.D. Vance to eliminate fraud, waste, and abuse within Federal benefit programs.

The Department of Justice’s Health Care Fraud Strike Force Program, currently comprised of eight strike forces operating in federal districts across the country, has charged more than 6,200 defendants who collectively billed federal health care programs and private insurers more than $45 billion since 2007. In addition, the Centers for Medicare & Medicaid Services, working in conjunction with the Office of the Inspector General for the Department of Health and Human Services, are taking steps to hold providers accountable for their involvement in health care fraud schemes.

ZIGUINCHOR, Senegal — Medical personnel from Austria and Italy will join Senegal and U.S. military medical personnel to conduct a multinational medical readiness exercise in southern Senegal as part of African Lion 2026, strengthening partnerships and improving readiness to deliver care in operational environments.

The exercise, held from April 25 to May 8, gathers U.S. Army medical professionals from the Vermont National Guard, Senegalese Armed Forces healthcare providers, and allied medical teams from Austria and Italy.

Training takes place at multiple medical facilities across the region. Working side by side, participating forces are exchanging expertise and refining their ability to provide effective care in complex environments.

Led by the U.S. Army Southern European Task Force, Africa (SETAF-AF), the MEDREX prepares military medical personnel to operate outside traditional clinical settings while strengthening multinational interoperability.

The training focuses on critical wartime medical skills, including point-of-injury care, blast and trauma management, surgical treatment and patient recovery through rehabilitation. These activities enhance both individual proficiency and unit readiness across participating forces.

“MEDREX allows our medical professionals to train in realistic environments while learning directly from our Senegalese and multinational partners,” said U.S. Army Col. Scot Tebo, command surgeon for SETAF-AF. “This collaboration improves how we deliver care in austere conditions and strengthens our collective ability to support forces during complex operations.”

The exercise reinforces enduring partnerships among participating nations and builds the trust and coordination needed to respond to shared security challenges.

Justice Department Files Complaint Against Minnesota Over Its Attempt to Override Federal Law

Note: View complaint here.

The Justice Department today filed a complaint against the State of Minnesota over its attempt to regulate global greenhouse gas emissions, which are subject to exclusive federal authority, and override the policy choices of the United States and other states to make energy affordable and reliable. The filing advances President Donald J. Trump’s executive order directing the Justice Department to protect American energy from state overreach. Specifically, the complaint seeks to stop the enforcement of Minnesota’s state court lawsuit that usurps exclusive federal authority and unreasonably burdens domestic energy development.

“President Trump promised to unleash American energy dominance, and Minnesota officials cannot undermine his directive by mandating that their woke climate preferences become the uniform policy of our Nation,” said Associate Attorney General Stanley Woodward. “Minnesota’s attempt to impose a national regulation on global greenhouse gas emissions not only is preempted by federal law, but also undermines affordable and reliable American energy, weakening the national and economic security of the United States.”

“The case we filed against Minnesota today is an attempt to rein in another unconstitutional state effort to invade an area of exclusive federal control,” said Principal Deputy Assistant Attorney General Adam Gustafson of the Justice Department’s Environment and Natural Resources Division (ENRD). “It is in America’s interest to have independent and secure sources of energy. Minnesota’s attempted overreach would undermine our economic and national security to advance the climate agenda of politicians and activists.”

According to the complaint filed today in U.S. District Court for the District of Minnesota, the state of Minnesota is attempting to regulate global greenhouse gas emissions by suing energy companies in state court to enjoin global energy production and compel them to disgorge their profits. As Judge Stras of the Eighth Circuit has recognized, such efforts to “set national energy policy” and “change the companies’ behavior on a global scale” are “beyond the limits of state law.”

These efforts are also preempted by the Constitution and the Clean Air Act. Last year, ENRD filed complaints against Hawaii, Michigan, New York, and Vermont to stop those states’ unconstitutional climate actions.

Chief of Staff and Senior Counsel John Adams of ENRD filed the complaint.
