Alan Dershowitz, a longtime Harvard law professor and frequent contributor to Fox News, said Thursday he could "enthusiastically" support Joe Biden over Donald Trump if the two meet in the 2020 presidential race.
But Dershowitz would not support Bernie Sanders, he said in a report from The Hill.
Speaking on The Dan Abrams Show on Sirius XM Dershowitz told host Dan Abrams that he has liked Biden "a long time."
"I'm a strong supporter of Joe Biden. I like Joe Biden. I've liked him for a long time, and I could enthusiastically support Joe Biden," Dershowitz said on the show.
Abrams then asked, "Over Donald Trump?"
"Over Donald Trump, yeah," Dershowitz said.
Dershowitz, who has said in previous interviews that he supported Hillary Clinton, said he didn't believe he could "pull that lever" for Sanders in the voting booth.
"If Bernie Sanders is nominated, that would present a real dilemma for me," Dershowitz said. "I don't think under any circumstances I could vote for a man who went to England and campaigned for a bigot and anti-Semite like Jeremy Corbyn. I don't think I could do it. I couldn't pull that lever."
Sanders, the independent Vermont senator who lost to Clinton in the 2016 Democratic primary, trails Biden in almost every poll for 2020 Democratic primary contenders.
Dershowitz has argued that a special counsel should have never been appointed to investigate Trump and any potential collusion with Russia during the 2016 presidential campaign.
In 2018, the New York Times noted that Dershowitz penned the book The Case Against Impeaching Trump in a rather quick turn around.
Dershowitz, a lifelong Democrat, has defended the president while many Democrats call for Trump's impeachment, and said criteria for impeachment is not there.
"Congress can't impeach President Trump," Dershowitz said. "The Constitution provides criteria for impeachment; treason, bribery, high crimes and misdemeanors."
He added that if Hillary Clinton had won the 2016 election and lawmakers attempted to impeach her, he would have stood up for her as well.
"I stand up for civil liberties no matter who the president is," Dershowitz said to Sean Hannity on Fox News. "If Hillary Clinton had been elected president and they were trying to impeach her, I would've written a book called 'The Case Against Impeaching Hillary Clinton.'"
