US President Donald Trump’s election campaign has cut ties with lawyer Sidney Powell on Sunday, saying that “she is not a member of the Trump Legal Team”, reported CNN.

Notably, at a news conference last week, the lawyer said that the electronic voting systems had switched millions of ballots to President-elect Joe Biden.

“Sidney Powell is practising law on her own,” campaign lawyers Rudy Giuliani and Jenna Ellis said in a statement. “She is not a member of the Trump Legal Team,” it added.

The announcement came after a federal judge on Saturday dismissed Donald Trump’s claims of widespread electoral fraud in Pennsylvania, dealing the latest blow to the incumbent’s bid to overturn his loss in the 2020 US presidential election.

Powell, a former federal prosecutor and a conservative activist did not respond to a request for comment.

Trump had referred to Powell as one of his lawyers in a November 14 tweet.

“Rudy Giuliani, Joseph diGenova, Victoria Toensing, Sidney Powell, and Jenna Ellis, a truly great team, added to our other wonderful lawyers and representatives,” the outgoing president tweeted.

Powell is currently representing Trump’s former national security adviser Michael Flynn to end a long-running criminal case against him.
