Senate Minority Leader Charles E. Schumer slapped a searing label on the Republican party Thursday, saying that if his colleagues across the aisle remain silent on the “culture of corruption” surrounding President Donald Trump, the GOP as a whole would be a “co-conspirator” with the president.

Trump’s former personal lawyer, Michael Cohen pleaded guilty to eight counts of campaign finance, bank loan, and tax fraud and directly implicated the president for directing him to commit a crime in a New York courtroom Tuesday.

Within minutes, roughly 200 miles south at a federal courthouse in Alexandria, Virginia, former Trump campaign chairman Paul Manafort was found guilty on eight charges of tax evasion and bank fraud after a three-week jury trial.

In a series of tweets Thursday, Schumer said Trump was “alleged to be an unindicted co-conspirator in a federal crime” for directing Cohen to make hush payments to two former mistresses, including adult film actress and director Stormy Daniels, in the months leading up to his 2016 election victory.

The New York Democrat criticized Republicans for backing Trump despite many of the controversial episodes that have rankled and sidetracked his campaign and administrative agenda since he took office, including the “Access Hollywood” tape in which he appears to brag about sexually assaulting women and the press conference in Helsinki, Finland, last month where he sided with Russian President Vladimir Putin over U.S. intelligence agencies by questioning whether Russia interfered in the 2016 election.
