US President Donald Trump’s defence team in his Senate trial will include special prosecutors from President Bill Clinton’s impeachment.
He will be represented by Ken Starr and Robert Ray, who investigated Mr Clinton, and Alan Dershowitz, whose past clients include OJ Simpson.
White House counsel Pat Cipollone and Mr Trump’s personal lawyer Jay Sekulow will lead the team, US media report.
Opening statements in the Senate trial are expected next week.
Former Florida Attorney General Pam Bondi has also reportedly been asked to join the team.
Mr Starr, Mr Ray and Mr Dershowitz will have speaking roles in the trial, according to Politico.
Mr Dershowitz told CBS News, the BBC’s US partner, that he had spoken with the president on Wednesday about the case.
“I agreed to do it as an independent constitutional scholar,” Mr Dershowitz, a retired Harvard University law professor, said. “I take no position on the politics – just on the Constitution.”
He added he was “very, very concerned” about the precedent this impeachment could establish.
“It could weaken the presidency and weaponise impeachment as a partisan tactic.”
Mr Dershowitz and Mr Starr both represented disgraced financier Jeffrey Epstein during his 2008 abuse trial.
Axios reported that some White House officials did not want Mr Dershowitz to join the team given his ties to Mr Epstein.
Mr Starr was the US Department of Justice independent counsel who investigated the Whitewater affair, a scandal-plagued mid-1980s land venture in Arkansas involving Bill and Hillary Clinton.
The inquiry ultimately uncovered unrelated evidence that Mr Clinton had been having an affair with a White House intern, Monica Lewinsky.
The investigation culminated in the Democratic president’s impeachment by the US House of Representatives in 1998. Mr Clinton was eventually acquitted by the Senate.
Mr Ray succeeded Mr Starr as the independent counsel.
Ms Lewinsky tweeted shortly after Mr Trump’s team was announced: “This is definitely an ‘are you kidding me?’ kinda day”, though she inserted an expletive.
Mr Trump was impeached by the US House of Representatives last month on charges of abuse of power and obstruction of Congress.
Democrats have accused him of withholding millions in military aid to Ukraine to pressure them into investigating his political rival, former Vice-President Joe Biden.
Mr Trump has denied these claims, calling the impeachment proceedings a partisan “hoax”.
