WASHINGTON – President Donald Trump has dubbed April 2 “Liberation Day,” promising to unveil a new round of aggressive tariffs on Wednesday, which he claims will free the U.S. from its reliance on foreign goods and bring hundreds of billions of dollars to the government.

But many congressional Republicans aren’t feeling very excited about being liberated. Like most economists, they worry about the negative effects of imposing across-the-board taxes on imports from other countries, fearing they will hike prices for their constituents and wreck the economy.

“Probably not,” Sen. Ron Johnson (R-Wis.) said when asked if he’ll be joining in Trump’s celebrations. “It’s a high-risk move on his part. I don’t know what his strategy is, but look at what the market’s reaction is. I have a similar reaction. I’m concerned.”

Other Republicans said they weren’t planning anything special for“Liberation Day.”

“Every day is a reason for celebration,” Sen. Thom Tillis (R-N.C.) deadpanned.

Markets have nosedived amid uncertainty over what Trump intended to do this week. Two of the three major U.S. markets closed out their worst quarter in March since 2022, back when Trump spent a large amount of his time blaming his predecessor, former President Joe Biden, anytime there was a selloff on Wall Street.

Even Sen. Tommy Tuberville (R-Ala.), a stalwart Trump ally, acknowledged that his constituents would feel pain if the president’s reciprocal tariffs are levied on nearly all American trading partners around the world.

“My people back in Alabama, you know, they’re all concerned about car tariffs, all those parts,” Tuberville said. “We have seven car manufacturers in our state, so you got parts that are coming in, it’s gonna raise prices. Prices are gonna come up.”

Trump defended his approach over the weekend, saying he “couldn’t care less” if his looming 25% tariffs raise the prices of foreign-made vehicles for Americans.

“I hope they raise their prices, because if they do, people are gonna buy American-made cars. We have plenty,” he told NBC News.

No cars sold to American consumers are fully made in the U.S. Most vehicles are assembled with imported parts that cross the country’s borders, sometimes several times, particularly across the U.S.-Canada border.

Republicans will get an opportunity to rebuke Trump over his tariffs on Canada, a longtime U.S. ally the president has threatened to annex, on Tuesday. The Senate is set to vote on a privileged legislation offered by Sen. Tim Kaine (D-Va.) that would block them from going into effect.

“President Trump’s taxes on Canadian goods have sent our economy into chaos, and Americans aren’t buying what he’s selling,” Kaine said in a statement ahead of the vote. “They know they will pay the price with higher costs for everyday items, and their confidence in the economy is the lowest it has been in recent years.”

The bill has no chance of making it to Trump’s desk even if it passes in the Senate, however. The GOP-controlled House changed its rules to disallow the possibility of taking up such a challenge to the president’s trade authorities in the government funding bill Congress passed last month.

Still, a few Republicans could join Democrats in voting against the Canada tariffs, including Sens. Rand Paul (R-Ky.) and Susan Collins (R-Maine), and possibly others. If the measure does pass, it would mark the first time Congress has pushed back against the Trump administration’s policies, even if symbolically.

That might be a bridge too far even for some Republicans who don’t like Trump’s tariffs.

Johnson told reporters on Monday, “I’m not going to be signing up to join Democrats in trying to poke a stick in President Trump’s eye.”
