Former Massachusetts Gov. Bill Weld, who is challenging President Trump on the Republican ticket in 2020, believes the recent actions of the White House and Trump campaign resemble those of former President Richard Nixon’s administration in the days before his impeachment.

“He’s [Trump] says [sic] we’re just not going to comply with any of these subpoenas because they’re partisans,” Weld told Boston Herald Radio’s “Morning Meeting” on Saturday. “And that to me is the president really not living up to his responsibility as a co-equal branch of government. In fact, it’s the House and the Senate that are in Article One of the Constitution, so they’ve got the primary power under the Constitution.”
