Washington, Feb 22 (AP) For a few hours on Friday, congressional Republicans seemed to get some relief from one of the largest points of friction they have had with the Trump administration. It didn't last.

The Supreme Court struck down a significant portion of President Donald Trump's global tariff regime, ruling that the power to impose taxes lies with Congress. Many Republicans greeted the Friday morning decision with measured statements, some even praising it, and party leaders said they would work with Trump on tariffs going forward.

But by the afternoon, Trump made clear he had no intention of working with Congress and would instead go it alone by imposing a new global 10 per cent import tax. On Saturday morning, he went further by saying he would raise that new tariff to 15 per cent.

He's doing so under a law that restricts the tariffs to 150 days and has never been invoked this way before. His decision could not only have major implications for the global economy, but also ensure that Republicans will have to keep answering for Trump's tariffs for months to come, especially as the midterm elections near.

“I have the right to do tariffs, and I've always had the right to do tariffs,” Trump said at a news conference, adding that he doesn't need Congress.

Tariffs have been one of the only areas where the Republican-controlled Congress has broken with Trump. Both the House and Senate at various points have passed resolutions intended to rebuke the tariffs being imposed on trade partners like Canada.

It's the rare issue where Republican lawmakers who came of age in a party that largely championed free trade have voiced criticism of Trump's economic policies.

“The empty merits of sweeping trade wars with America's friends were evident long before today's decision,” Sen. Mitch McConnell, the former longtime Senate Republican leader, said in a statement, adding that tariffs raise the prices of houses and disrupt other industries important to his home state of Kentucky.

At least one Republican congressman who last week voted against Trump's tariffs on Canada is now facing political consequences. Trump on Saturday posted on his Truth Social platform that he was rescinding his endorsement of Colorado Rep. Jeff Hurd for reelection over his lack of support for tariffs and instead supporting Hurd's Republican primary competitor, Hope Scheppelman.

“Congressman Hurd is one of a small number of Legislators who have let me and our Country down,” Trump wrote. “He is more interested in protecting Foreign Countries that have been ripping us off for decades than he is the United States of America.” How Democrats plan to leverage Trump's trade war ------------------------------------------------------ Democrats, looking to win back control of Congress, intend to make McConnell's point their own. At a news conference Friday, Senate Democratic Leader Chuck Schumer said Trump's new tariffs “will still raise people's costs and they will hurt the American people as much as his old tariffs did.” Schumer challenged Republicans to stop Trump from imposing his new global tariff. Democrats on Friday also called for refunds to be sent to U.S. consumers for the tariffs struck down by the Supreme Court.

“The American people paid for these tariffs and the American people should get their money back,” Sen. Elizabeth Warren, D-Mass., said on social media.

It all played into one of the Democrats' central messages for the midterm campaign: that Trump has failed to make the cost of living more affordable and has inflamed prices with tariffs.

Midsize US businesses have had to absorb the import taxes by passing them along to customers in the form of higher prices, employing fewer workers or accepting lower profits, according to an analysis by the JPMorganChase Institute.

Will Congress act on Trump's new tariffs? ------------------------------------------- The Supreme Court decision on Friday made it clear that a majority of justices believe that Congress alone is granted authority under the Constitution to levy tariffs. Yet Trump quickly signed an executive order citing the Trade Act of 1974, which grants the president the power to impose temporary import taxes when there are “large and serious United States balance-of-payments deficits” or other international payment problems. The authority has never been used and therefore never tested in court.

Republicans at times have warned Trump about the potential economic fallout of his tariff plans. Yet before Trump's “Liberation Day” of global tariffs in April last year, Republican leaders declined to directly defy the president.

Some GOP lawmakers cheered on the new tariff policy, highlighting a generational divide among Republicans, with a mostly younger group of Republicans fiercely backing Trump's strategy. Rather than adhering to traditional free trade doctrine, they advocate for “America First” protectionism, hoping it will revive US manufacturing. (AP) MNK MNK

Congressional authority over tariffs affirmed, but executive invoked temporary trade statute to impose new global import tax. A majority of justices held that the power to levy tariffs is vested in Congress, voiding a major part of the presidential global tariff program; the President then invoked the Trade Act's temporary emergency authority to impose a new short-term global import tax, a provision never previously used this way, raising questions about the statute's reach and prompting political fallout, calls for consumer refunds, and intensified partisan divisions over trade policy.
