Trump admin live updates: Trump warns of 'large scale tariffs' on EU and Canada

President Donald Trump's Cabinet meeting began with officials touting "waste, fraud and abuse" they claim to have identified at their various agencies, including the Small Business Administration, Department of Agriculture and the Environmental Protection Agency.

Trump, though, admitted it is "not necessarily a very popular thing" to make cuts to staff.

"You know, you're talking about employment, you're talking about people and the lives of people. And yet, I think the American public understands we're trying to save our country and make our country great again," Trump said.

"And I have no idea how it plays out in the public," he continued. "I have --I guess you see, poll numbers that have very good numbers, but I don't know what that means long term. But it's something that has to be done."

Polls have shown that while Americans support efficiency and progress in broad terms, they don't like some of the specifics of what the administration's done.

President Donald Trump's plan for reciprocal tariffs on April 2 is expected to be more targeted than what he has threatened previously, but the situation remains fluid and the plan is still under discussion, sources familiar with the plan told ABC News.

The April tariffs would still be a significant increase in U.S. tariffs and are expected to strain relations with U.S. allies, but it will likely be narrower than what Trump has previously said. In February, Trump ordered federal agencies to look into virtually every U.S. trading partner to evaluate what reciprocal tariff rate to put on them.

"April 2nd is Liberation Day in America!!!" Trump wrote on Truth Social. "For DECADES we have been ripped off and abused by every nation in the World, both friend and foe. Now it is finally time for the Good Ol' USA to get some of that MONEY, and RESPECT, BACK. GOD BLESS AMERICA!!!"

Trump's officials have also been signaling there will be a more focused approach in recent interviews.

"One of the things we see from markets is they're expecting they're going to be these really large tariffs on every single country," Kevin Hassett, Trump's National Economic Council director, told Fox News. "I think markets need to change their expectations, because it's not everybody that cheats us on trade, it's just a few countries and those countries are going to be seeing some tariffs."

House Judiciary Chairman Jim Jordan said on Monday his committee intends to hold hearings next week on U.S. District Judge James Boasberg, who blocked deportations under the Alien Enemies Act, and other recent judicial rulings.

"It really starts to look like Judge Boasberg is operating purely political against the president, and that's what we want to have hearings on this broad issue and some of what Judge Boasberg is doing. And so, we're going to start those next week, and we think Sen. Grassley is going to do the same," Jordan said on Fox News. Sen. Chuck Grassley is the chairman of the Senate Judiciary Committee.

In addition to hearings, Jordan said he expects House Republican leadership to put California Republican Rep. Darrell Issa's bill entitled "No Rogue Rulings Act" on the floor for a vote next week. It's not clear when the vote would be held, but the legislation would put restrictions on district court judges issuing orders providing injunctive relief decisions that impact the entire country outside their districts.

President Donald Trump is meeting with his Cabinet at the White House, with Elon Musk also in attendance.

The White House is calling this the president's second Cabinet meeting. During the first meeting back in late February, Musk spoke at length to defend the Department of Government Efficiency's work -- especially its cuts to the federal workforce.

ABC News reported a clash between Musk and Secretary of State Marco Rubio in a separate meeting of some Cabinet officials earlier this month, with Musk accusing Rubio of not carrying out sufficient firings at his agency. Trump denied any bad blood between the two men.
