The 16 attorneys, many of whom worked in Republican administrations, wrote in a joint statement to be released Thursday morning that Trump’s now infamous call with Ukrainian President Volodymyr Zelensky, the text messages between diplomats and Trump’s public call for China to investigate a political opponent are “undisputed” events that amount to Trump violating his oath of office.

“We have not just a political candidate open to receiving foreign assistance to better his chances at winning an election, but a current president openly and privately calling on foreign governments to actively interfere in the most sacred of U.S. democratic processes, our elections,” they wrote…

Don Ayer, who served as deputy attorney general under President George H.W. Bush, said he found it “inexplicable” that other Republicans were sticking by Trump.

“I am disgusted by the conduct of Republican senators who pose as reputable people, but shamelessly hide under rocks instead of calling out the president’s horrendous behavior as the gross misconduct that they know it to be,” he said.
