President Donald Trump escalated his attacks on Attorney General Jeff Sessions on Monday, suggesting the Department of Justice put Republicans in midterm jeopardy with recent indictments of two GOP congressmen. "Two easy wins now in doubt because there is not enough time", Trump said in his tweet.
Collins, a Republican who represents the area between Buffalo and Rochester, was the first member of Congress to endorse Trump's candidacy.
He tweeted: "This is a awful situation and Attorney General Jeff Sessions should stop this Rigged Witch Hunt right now, before it continues to stain our country any further".
The attack on Mr Sessions comes after Mr Trump last week said that Mr Sessions was safe in his job at least until after the November mid-term elections.
Collins was accused in a 30-page indictment of tipping off his son - while attending the picnic - about the results of a failed drug trial that was about to crash the stock price of an Australian biotech company. Fox News has reached out to the White House for additional clarification, and the Justice Department did not immediately respond.
Monday's tweets continued a long-running gripe Trump has had with Sessions ever since the attorney general recused himself previous year from the Russian Federation investigation. Same thing with Lyin' James Comey.
Trump on Sunday mounted a massive attack against Sessions, blaming him for allowing charges to be brought against two GOP congressman.
During his arraignment, Hunter threw his wife under the bus, whining that she was in charge of his personal and congressional spending.
The Hunter investigation began in June 2016, according to the indictment. After the recusal, Deputy Attorney General Rod Rosenstein appointed Special Counsel Robert Mueller to lead the probe, which Trump calls a "witch hunt". Trump did not have any public events Monday.
The tension between Trump and Sessions boiled over recently with Sessions punching back, saying that he and his department "will not be improperly influenced by political considerations".
