President Donald Trump signed a proclamation on Wednesday banning travel from 12 countries, citing national security concerns.

The administration is imposing full restrictions on entry into the United States from nationals of Afghanistan, Burma, Chad, the Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan and Yemen.

Additionally, Trump is imposing partial restrictions on entry from nationals of seven other countries: Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan and Venezuela.

"As President, I must act to protect the national security and national interest of the United States and its people. I remain committed to engaging with those countries willing to cooperate to improve information-sharing and identity-management procedures, and to address both terrorism-related and public-safety risks," Trump wrote.

Canadian Prime Minister Mark Carney said the U.S. steel and aluminum tariffs are “unlawful and unjustified,” in comments to the Canadian House of Commons Wednesday.

Carney said this is why Canada has “implemented retaliatory tariffs on over $90 billion worth of US goods.”

“The newly imposed American tariffs on steel and aluminum are both unlawful and unjustified. That’s why we’ve implemented retaliatory tariffs on over $90 billion worth of U.S. goods. We are engaged in intensive negotiations with the U.S., while also preparing additional reprisals should those talks fail,” Carney added.

As the Senate weighs possible changes to the state and local tax (SALT) deduction cap as part of the tax portion of the "big, beautiful bill," House Republicans from blue states are already threatening to derail the bill's prospects.

"Let's be clear — no SALT, no deal," New York Republican Mike Lawler said Wednesday in a post on X.

New York Rep. Nick LaLota was on the same page, posting on X: "No SALT. No Deal. For Real."

The House-passed bill raises the deduction limit of state and local taxes from federal income tax filing from $10,000 to $40,000 for joint filers making less than $500,000 per year. The cap increases then by 1% every year thereafter.

Thune signaled changes could be coming to the SALT deal that was struck in the House but the details are still unclear.

"It would be very, very hard to get the Senate to vote for what the House did," Thune told reporters. "We've just got some people that feel really strongly on this."

Senate Minority Leader Chuck Schumer took aim at the Republican spending bill at a news conference on Wednesday afternoon where he spoke in front of posters calling the funding bill "Well, We're All Going to Die Act," citing Sen. Joni Ernst's controversial comments from last week.

The CBO report found that 10.9 million Americans would be uninsured by 2034 because of the bill.

"This is health care across the board," Schumer said.

Schumer noted that Ernst's comments, "summed up" the entire Republican stance on the bill.

"This is an across-the-board disaster for the American people," Schumer claimed.
