Trump admin updates: US military is preparing for possible activation of National Guard in DC

Bruce Reed, who served as the deputy chief of staff for policy under former President Joe Biden, is set to appear for an interview with the House Oversight Committee on Tuesday.

The Republican-led committee has interviewed several people close to Biden in its probe into the former president's mental fitness in office, including interviews last week with former senior adviser Mike Donilon and former counselor Steve Ricchetti.

There have been varying degrees of cooperation from those who have been called in for interviews. Former Chief of Staff Ron Klain cooperated with the committee for several hours; Ricchetti appeared voluntarily. Other aides have not been willing to engage with the committee and invoked the Fifth Amendment, including Dr. Kevin O'Connor, the former physician to Joe Biden, and Annie Tomasini, who served as the deputy chief of staff to Biden.

As a standoff in Texas persists, President Donald Trump weighed in Tuesday amid the heightened tensions in a phone interview on CNBC, arguing Republicans are "entitled" to more seats in Congress.

"We have an opportunity in Texas to pick up five seats. We have a really good governor, and we have good people in Texas. And I won Texas. I got the highest vote in the history of Texas, as you probably know, and we are entitled to five more seats," Trump claimed.

Some Democratic governors are working on plans to potentially draw new Congressional maps to favor Democrats in an effort to counter efforts from Republicans in Texas.

Trump criticized the move, using it as an argument for the efforts in Texas to continue.

"That's all gerrymandered. California is gerrymandered. We should have many more seats in Congress. In California, it's all gerrymandered," he said.

Georgia Rep. Marjorie Taylor Greene wants President Donald Trump to commute the sentence of former disgraced New York Congressman George Santos, who recently reported to federal prison.

The congresswoman, a close ally of the president, sent a letter on Monday to the Office of the Pardon Attorney requesting that Trump commute Santos’ sentence.

“I wholeheartedly believe in justice and the rule of law, and I understand the gravity of such actions. However, I believe a seven-year sentence for such campaign-related matters for an individual with no prior criminal record extends far beyond what is warranted,” Rep. Greene said in the letter.

Rep. Greene says Santos’ crimes “warrant punishment,” but says the sentencing “is an abusive overreach by the judicial system.”

“Commuting his sentence would acknowledge the severity of his actions and simultaneously provide a path forward in allowing him to make amends for his crimes and strive to better serve the people in his community,” the letter states.

The move by Rep. Greene comes after Trump said during an interview on Newsmax that aired Friday that no one talked to him about a pardon for Santos when asked if he’d be open to granting him one.

Trump said Santos’ seven-year sentence was a “long time,” but was quick to point out “he lied like hell.”

President Donald Trump will sign an executive order on Tuesday creating a task force to help oversee the 2028 Olympics in Los Angeles, a White House official confirmed to ABC News.

"The creation of this task force marks an important step forward in our planning efforts and reflects our shared commitment to delivering not just the biggest, but the greatest Games the world has ever seen in the summer of 2028," Casey Wasserman, the chairperson and president of LA28, said in a statement about the task force.

The task force was first reported by the Hollywood Reporter.

Trump has long touted that he helped secure the 2028 Olympics in the U.S. during his first term and has expressed his excitement for the event.

“The President considers it a great honor to oversee this global sporting spectacle in his second term. Sports is one of President Trump’s greatest passions, and his athletic expertise, combined with his unmatched hospitality experience, will make these Olympic events the most exciting and memorable in history," White House Press Secretary Karoline Leavitt said in a statement about the task force.
