On April 8th, according to the US media Axios, < b > Trump will veto legislation proposed by Democratic Senator Maria Cantwell of Washington and Republican Senator Chuck Grassley of Iowa to limit the president's unilateral tariff authority. Seven Republican senators have signed the bipartisan legislation , which is becoming a way for Republicans to express their concerns about Trump's tariff policy. "It's not often that a bill is first introduced with this much support, but I think it shows the anxiety," Cantwell said. According to a person familiar with Trump's thinking, Trump is annoyed by the introduction of the bill. "If this bill is passed, it would interfere with the President's authority and responsibility to shape our foreign policy and protect our national security," said a government policy statement sent to the congressional office today. "If passed by Congress and sent to the President, he will veto the bill."
