Former US President Donald Trump has announced a new impeachment legal defense team before his Senate trial.

The two representing Trump will be defence lawyer David Schoen, a frequent television legal commentator, and Bruce Castor, a former district attorney in Pennsylvania who has faced criticism for his decision to not charge actor Bill Cosby in a sex crimes case.

Both attorneys issued statements through Trump’s office saying that they were honored to take the job.

“The strength of our Constitution is about to be tested like never before in our history. It is strong and resilient. A document written for the ages, and it will triumph over partisanship yet again, and always,” said Castor, who served as district attorney for Montgomery County, outside of Philadelphia, from 2000 to 2008.

The announcement was intended to promote a sense of stability surrounding the Trump defense team as his impeachment trial nears.

The former president has struggled to hire and retain attorneys willing to represent him against charges that he incited the deadly riot at the US Capitol, which happened when a mob of loyalists stormed Congress as lawmakers met Jan. 6 to certify Joe Biden’s electoral victory.

That’s a contrast from his first impeachment trial, when Trump’s high-profile team of attorneys included Alan Dershowitz, one of the best-known criminal defense lawyers in the country, as well as White House counsel Pat Cipollone, and Jay Sekulow, who has argued cases before the Supreme Court.

Trump’s team had initially announced that Butch Bowers, a South Carolina lawyer, would lead his legal team after an introduction from Republican Sen. Lindsey Graham. But that team unraveled over the weekend due to differences over legal strategy.
