Four Senate Republicans collaborated with Democrats to issue a rare bipartisan criticism of President Donald Trump’s trade policy.

The Senate approved a resolution with a vote of 51 to 48, aimed at preventing the Trump administration from implementing proposed tariffs on Canadian imports. The four Republicans who sided with the Democrats included Sens. Rand Paul, who co-sponsored the resolution, along with Susan Collins, Mitch McConnell, and Lisa Murkowski, as reported by CNN.

This action signifies an unusual instance of bipartisan dissent against Trump within the GOP-controlled Senate, particularly following Trump’s remarks urging Republicans to oppose the measure.

While the Senate vote may primarily hold symbolic significance, House GOP leaders are not anticipated to take any steps to challenge Trump’s tariff policy, having previously moved to obstruct such actions. Nevertheless, some House Democrats believe they may have discovered a way to circumvent GOP leadership regarding tariffs, according to CNN.

The Democrat-led Senate initiative to contest the administration’s trade policy has been in development for some time and was not directly triggered by Trump’s tariff announcements on Wednesday. The resolution aims to overturn a national emergency declaration that the Trump administration utilized in February to announce the planned tariffs on Canadian imports. Democrats have positioned the measure as a means to reverse the tariffs on Canadian goods, CNN reported.

On Wednesday, Trump announced tariffs of at least 10% on nearly all goods entering the United States, with even higher rates for countries with significant trade deficits with the U.S.

This new policy represents a significant shift in global trade and economic strategy, aiming to restore U.S. manufacturing strength and balance trade. However, it poses the risk of escalating a global trade war and increasing prices for American consumers at a crucial time for the economy, CNN noted.

Rep. Greg Meeks of New York, the leading Democrat on the House Foreign Affairs Committee, stated on Wednesday that he intends to introduce a privileged resolution to compel a House vote on tariffs. This procedural maneuver allows him to bypass leadership and advocate for a floor vote.

Democratic Sen. Tim Kaine, who led the initiative to prompt the Senate vote against the Trump administration’s tariffs on Canadian imports, disclosed on Wednesday that he had approached McConnell the night before to discuss the effort. Kaine mentioned that the Kentucky Republican expressed his support even before he could make the request, according to CNN.

“I said, I want to talk to you about my Canadian tariffs bill. And you know, I didn’t even get to the question, and he said, ‘I’m with you,’” Kaine recounted to CNN, describing their conversation.

During a Rose Garden event announcing the tariffs, Trump predicted that Americans who are currently skeptical of his actions will eventually recognize that he made the right choice.

“This is one of the most important days, in my opinion, in American history. It’s our declaration of economic independence. For years, hardworking American citizens were forced to sit on the sidelines as other nations got rich and powerful, much of it at our expense,” the president stated.

“This will be a very big moment,” Trump added. “I think you’re going to remember today. It’s going to be a free nation that we’re dealing with. We’re going to have a very free and beautiful nation. It’s going to be Liberation Day in America, and it’s going to be a day that, hopefully, you’re going to look back in years to come and you’re going to say, you know, he was right.”

Trump concluded his remarks by saying, “This has turned out to be one of the most important days in the history of our country. God bless you, and God bless America. Thank you, everybody. Thank you very much.”

On Wednesday, Wall Street opened lower, with the Dow Jones, NASDAQ, and S&P 500 all declining by 2-3 percent before the opening bell.
