In today's episode of "The Emperor's New Clothes," Alysin Camerota had some news about rising Republican unrest over Trump's proposed Mexico tariffs.

"Back here at home, the possibility of a Republican rebellion. You heard me right. Republican senators aren't happy about the president's threat to impose tariffs on Mexico. They are considering their next actions. Lauren Fox is live on Capitol Hill with the latest. What's the plan, Lauren?" Camerota said.

"The GOP lunch did not go well yesterday," Fox said. "Members and aides I spoke with after the lunch basically said White House officials and Justice officials in the room could not explain exactly how the president's tariffs would be enacted, whether or not he would issue a new emergency declaration, whether he could amend the old one. A lot of legal questions up in the air. One aide basically said the meeting was 'a cluster****' and used an expletive to describe it. A storm brewing at home within the president's own party concerning his threat to impose tariffs against Mexico over border security."

"President Trump dismissing any possibility that GOP lawmakers would stand in his way."

"Starting next Monday, President Trump is vowing to enforce a 5% tariff on all goods in Mexico. Those levels could go as high as 25% by October. Trump says it's punishment for Mexico not doing enough to stop Central American migrants from coming to the U.S.

"For some Republican lawmakers, the tariffs aren't justified," Fox said.

"A person who attended a private meeting says multiple GOP senators expressed frustrations there, saying the White House is unable to explain how President Trump's tariffs would work," Fox said. "The senators pushing to hold off on moving forward until Mr. Trump briefs them personally. The Democratic-controlled House is likely to shut down any new emergency declaration from President Trump to justify tariffs. So republican senators will have to choose between voting against Trump or voting for tariffs they can't support."
