President Trump appears to be taking his fallout with former personal attorney Michael Cohen to a new level.

As of Thursday evening, Trump's personal account was no longer following Cohen.

"realDonaldTrump appears to no longer follow @MichaelCohen212. (This bot cannot tell if this was an unfollow, suspension or block.)," the account that monitors Trump's Twitter activity wrote in a post.

However, Cohen still follows @RealDonaldTrump as well as @POTUS, the official government page for Trump. He also follows some of Trump's family members, including his adult children Ivanka Trump and Donald Trump Jr.

The two men had been friends for decades, and Cohen had represented Trump as his lawyer.

Cohen, who once said he would "take a bullet" for Trump, decided earlier this summer to act against him. Cohen's own attorney, Lanny Davis, said in August that Cohen changed his mind after Trump's press conference with Russian President Vladimir Putin this summer.

"He certainly found Donald Trump unsuitable to hold the office after Helsinki," said Davis. "He worried about the future of our country with somebody who was aligning himself with Mr. Putin and denying what his entire intelligence community — his own appointees have said is an indisputable fact that Putin interfered with our presidential election on behalf of President Trump, and he still denies that."

Cohen turned on Trump after he was caught up in the New York attorney general office's investigation into payments Cohen made to porn star Stormy Daniels on behalf of his boss during the 2016 election. Cohen said Trump told him to violate campaign finance laws.

Cohen pleaded guilty in August to five counts of tax evasion from 2012 to 2016, one count of making a false statement to a financial institution, one count of willfully causing an unlawful corporate contribution, and one count of making an excessive campaign contribution.

Trump joked at the time that he wouldn't recommend anyone hire Cohen as a lawyer.

"If anyone is looking for a good lawyer, I would strongly suggest that you don’t retain the services of Michael Cohen!" Trump wrote on Twitter in August.
