Trump's Canada tariff fight reaches critical point as House GOP summons trade chief

FIRST ON FOX: President Donald Trump's top trade advisor will huddle with House Republicans on Wednesday as the commander-in-chief's tariff strategy is quickly becoming a flashpoint on the campaign trail.

Trade Representative Jamieson Greer is attending the Republican Study Committee's weekly lunch this week, a source familiar with planning told Fox News Digital.

Two additional sources told Fox News Digital they expect lawmakers to raise the issue of Trump's trade war with Canada.

Trump accused Ontario of ripping off American businesses in a post on Truth Social Sunday, claiming Canada wants "to be treated like a state, but they aren't one." ‘CAPTAIN CANADA’ FIREBRAND UNLOADS ON TRUMP WITH PROFANE ONE-LINER AS TRADE WAR ESCALATES "They’ve been ripping us off for decades, and it’s going to stop," Trump wrote.

The U.S. imposed a 50% tariff on a range of Canadian goods in late July, with the duties going into effect earlier this month.

Canada responded with its own tariffs of up to 50% on U.S. imports.

TRUMP JUST EXPANDED HIS TARIFF PLAYBOOK WITH A POWERFUL TRADE WEAPON NO PRESIDENT HAS EVER USED Trump also escalated tensions with the country this month by signing an executive order to rename Lake Ontario as "Lake America." It's not clear when the meeting between Greer and RSC was planned, nor is it clear if Fox News Digital's sources expect questions or outright opposition to the trade war.

But Trump's tariffs have been a political lightning rod for much of his second term.

The House passed a bill in February aimed at reversing Trump's earlier Canada tariffs , with six Republicans voting in support.

Just one Democrat, Rep.

Jared Golden, D-Maine, voted against it.
