Trump says 3rd term isn't a joke, despite term limit

President Donald Trump signed an executive order aimed at cutting down immigrants without legal status on voter rolls.

Will Scharf, the White House staff secretary, said the order ensures that "the Department of Homeland Security and the data that they have available is being fully weaponized to ensure that illegal immigrants aren't voting."

The order instructs that federal funding be cut from states that don't take steps to "secure" their elections and calls on the Department of Justice to prosecute election crimes in states the administration says are not "in compliance with federal law around election integrity."

It also calls for the election assistance commission to require documented proof of U.S. citizenship on mail-in voter registration. Documentation can include a U.S. passport, a military ID, a state or federally issued ID, or a REAL ID that indicates citizenship.

It is already illegal for non-U.S. citizens to vote in state and federal elections, and reports of noncitizens voting in elections are very rare, according to research from the Brennan Center for Justice.

A federal judge has temporarily blocked the Trump administration from shutting down Radio Free Europe/Radio Liberty.

U.S. Judge Royce Lamberth issued a temporary restraining order Tuesday afternoon that blocked the dismantling of the organization, finding the Trump administration’s attempt to defund the group was “unsupported by any facts or reasoning” and likely violated federal law.

“The leadership of [United States Agency for Global Media] cannot, with one sentence of reasoning offering virtually no explanation, force RFE/RL to shut down—even if the President has told them to do so,” wrote Judge Lamberth, a Reagan appointee.

Earlier this month, Trump signed an executive order directing multiple agencies including the US Agency for Global Media – which oversees Radio Free Europe/Radio Liberty – to reduce to cut their functions to the minimum required by law. Radio Free Europe/Radio Liberty sued last week to block the Trump administration from terminating its federal funding.

President Donald Trump was asked if anyone would be fired as a result of a journalist being inadvertently added to a group chat with top administration officials discussing a military operation in Yemen.

"We've pretty much looked into it. It's pretty simple, to be honest," Trump said. "It's not -- it's just something that can happen. It can happen."

Speaking on the use of Signal, Trump said, "It's not a perfect technology. There is no perfect technology."

Trump repeatedly said the information included in the chain was not classified. He did not respond to a shouted question from a reporter on who determined the material involved wasn't classified.

President Donald Trump was asked about the continued use of Signal among government offices and if things would change, and the president said he would look into it.

"It has to deal with security. Are people able to break into conversations and if true we have to find some other form or device," he said.

National security adviser Mike Waltz, who repeatedly tried to change the subject during the presser, added that the White House's legal team and tech team are looking into it.

"We're going to keep everything as secure as possible. No one in your national security team would ever put anyone in danger," he said.
