Trump admin live updates: Trump pardons former entertainment exec indicted by own DOJ

Democratic Sen. Mark Kelly will hold a news conference in the Capitol at 3:30 p.m. on Monday to address what he calls Trump and Defense Secretary Pete Hegseth's "effort to intimidate" him.

Kelly was one of the six lawmakers who appeared in a video last month telling military members that they could refuse illegal orders.

The Department of Defense last week said it would launch a "thorough review" into Kelly, citing "serious allegations of misconduct."

In the video, the group says, "The threats to our Constitution aren't just coming from abroad, but from right here at home. Our laws are clear. You can refuse illegal orders. No one has to carry out orders that violate the law or our Constitution."

During a gaggle with reporters aboard Air Force One on Sunday night, Trump said he would release the results of his MRI and said he didn't know what part of the body the scan was targeting.

Trump was asked about calls from Democrats for him to release the results of the MRI that he revealed he got during an appointment at Walter Reed Medical Center in October.

"But if you want to have it released, I'll release it, absolutely," Trump said Sunday.

A reporter than asked what the MRI was looking at, to which Trump replied he didn't know.

"I have no idea. It was just an MRI. What part of the body? It wasn't the brain. Because I took a cognitive test and I aced it," Trump said.

President Donald Trump said in a social media post on Monday that the United States is "very satisfied" with the results in Syria after the nation has seen new leadership and also warned that Israel should not do anything to "interfere with Syria's evolution into a prosperous State."

"We are doing everything within our power to make sure the Government of Syria continues to do what was intended, which is substantial, in order to build a true and prosperous Country," Trump wrote.

Trump also issued a call for Israel and Syria to maintain good relations.

"It is very important that Israel maintain a strong and true dialogue with Syria, and that nothing takes place that will interfere with Syria's evolution into a prosperous State. The new President of Syria, Ahmed al-Sharaa, is now working diligently to make sure good things happen, and that both Syria and Israel will have a long and prosperous relationship together," Trump said in the post.

Trump's comments come after Syria's new president, Ahmed al-Sharaa, visited the White House last month.

The United States and the United Kingdom have reached a deal on pharmaceutical tariffs that exempts pharmaceuticals imported into the U.S. from the U.K. from those duties in exchange for the U.K.'s health system agreeing to pay more for new medicines.

The U.S. will exempt U.K. "pharmaceuticals, pharmaceutical ingredients, and medical technology from Section 232 tariffs" and will not put other sector-specific tariffs on U.K. drugs for the rest of President Donald Trump's term, according to a press release from the U.S. Trade Representative's office about the agreement in principle.

According to the release about the deal, the U.K.'s National Health Service will increase the "net price it pays for new medicines by 25%." The U.K. will also ensure that higher prices are not eroded by any factors as part of the deal.

This agreement comes after the nations agreed to further negotiations on drug pricing as part of the framework of a trade deal that nations reached in May.

"The Trump administration is reviewing the pharmaceutical pricing practices of many other U.S. trading partners and hopes that they will follow suit with constructive negotiations," U.S. Trade Ambassador Jamieson Greer said in a statement about the move.
