A Justice Department official said the department provided a "written proposal" to Cornyn's staff Tuesday. "Has there been a written agreement of the parties to modify the settlement fund?" Speaking to reporters in the Oval Office, Mr. Trump suggested Cornyn's opposition stemmed from his endorsement of his primary opponent, Texas Attorney General Ken Paxton. "Maybe John Cornyn is upset with me because I didn't endorse him," Mr. Trump said. In response to Mr. Trump, Cornyn said: "That's a convenient excuse, and it happens to be untrue."
