President Trump’s former personal attorney, Michael Cohen, urged his followers to vote next month, declaring that the midterms “might be the most important vote in our lifetime.”

Cohen’s plea for voter turnout comes days after he and his lawyer confirmed that he’d re-registered as a Democrat after recently serving as the deputy finance chairman of the Republican National Committee (RNC).

{mosads}Democrats need to pick up 23 seats in the House next month to win back control of the lower chamber. The party must pick up two Senate seats to do the same in the upper chamber, though a number of vulnerable Democratic senators are up for reelection.

Cohen until June served as the RNC deputy finance chairman. He resigned after federal prosecutors began investigating him for bank fraud, tax fraud and campaign finance law violations.

Cohen has in recent months given indications he is opposing the president after working for Trump as his personal lawyer at the Trump Organization.

In August, Cohen pleaded guilty in federal court in Manhattan to bank and tax fraud, as well as campaign finance law violations relating to payments to buy the silence of two women claiming they had affairs with Trump in 2006. Cohen told the court that he violated campaign finance laws at Trump’s direction.

While his plea deal did not include an agreement to cooperate with federal investigators, ABC reported last month that Cohen voluntarily agreed to sit for interviews with special counsel Robert Mueller as part of the investigation into Russian interference in the 2016 election.

In addition to the Mueller investigation, Cohen has reportedly cooperated with a separate investigation led by New York state investigators into the Trump Foundation, ABC reported.

Following Cohen’s guilty plea, Trump attacked his former attorney’s credibility, claiming without evidence that Cohen lied to get a better deal, and suggesting the practice of “flipping” to cooperate with prosecutors “almost ought to be illegal.”
