For the first time, Sen. Bernie Sanders (I-Vt.) said Thursday that President Donald Trump should consider resigning the nation's top office.

Speaking on "CBS This Morning," Sanders addressed allegations of sexual misconduct against Sen. Al Franken (D-Minn.) and Alabama Senate candidate Roy Moore. He noted that Trump had faced similar accusations during the 2016 presidential campaign and referred to a 2005 "Access Hollywood" tape in which Trump bragged about groping women.

"We have a president of the United States who acknowledged on a tape widely seen all over this country that he's assaulted women, so I would hope that maybe the president of the United States might pay attention [to] what's going on and also think about resigning," Sanders said.

Later Thursday, the Vermont senator and 2016 presidential candidate restated his call on Twitter:

We have a president who acknowledged on tape that he assaulted women. I would hope that he pays attention to what's going on and think about resigning.

According to Daniel McLean, a spokesperson for Sanders, the senator had not previously called on Trump to consider resigning.
