Trump admin live updates: Dems react to Hegseth discussing Yemen strike in 2nd chat

President Donald Trump signed an executive order on Tuesday rescinding two executive actions issued by former Presidents Jimmy Carter and Bill Clinton that constrain federal office locations.

According to a fact sheet provided by the White House, Trump’s executive order allows "federal agencies to select office space and facilities based on cost-effectiveness, mission suitability, and the needs of the American people."

The administrator of the General Services Administration will be tasked with updating federal office space management regulations to conform with the order.

The White House argues in its fact sheet that by eliminating the executive actions from Carter and Clinton the Trump administration is making it easier to bring federal services to Americans.

Trump signed an executive order Tuesday aimed at lowering healthcare and prescription drug costs.

The order included a directive to improve the program for Medicare to negotiate drug prices, plans to create a program to get better prices for the most expensive drugs, including insulin and directed the FDA to approve state importation programs and approvals for generic drugs.

According to a fact sheet about the order, the government is looking to "eclipse the 22% in savings achieved" by the first year of Medicaid's program to negotiate drug prices. The order also says that the government plans to align the payment with what hospitals pay for them, which the White House says is sometimes "35% lower than what the government" pays.

The order also aims to standardize Medicare costs of drugs regardless of care facility, which the White House says can lower prices by as much as 60%.

Dan Caldwell, a senior adviser to Defense Secretary Pete Hegseth, has been placed on administrative leave as part of a leak investigation, a U.S. official told ABC News on Tuesday.

Caldwell is a longtime adviser to Hegseth, long before he was named to be the secretary of defense, and was placed on leave following an "unauthorized disclosure," Reuters reported.

On March 21, Joe Kasper, the Defense Department’s chief of staff, directed the "Director for Defense Intelligence (Counterintelligence, Law Enforcement, and Security) to support OSD in leading an investigation into unauthorized disclosures of sensitive and classified information across the Department of Defense."

That memo authorized the use of polygraphs that will be inline with "applicable law and policy" for an investigation that he said would begin immediately.

It is unclear if Caldwell underwent a polygraph.

Asked if Russia agreed to anything in its meeting with U.S. special envoy Steve Witkoff, White House press secretary Karoline Leavitt said she didn't want to get ahead of those negotiations but added that there is an "incentive" for Russia to end its war on Ukraine.

Trump spoke with the sultan of Oman Tuesday, who helped facilitate talks between the United States and Iran over the weekend, Leavitt confirmed during the briefing.

"As you know, an additional negotiation between Steve Witkoff and Iran's representative has been scheduled for Saturday. And since these are ongoing negotiations, I have nothing more to add on that," she added.
