Senator Al Franken is facing calls for his resignation from fellow Democratic colleagues after a new allegation surfaced of inappropriate conduct.
His office said that he would make an announcement on Thursday. Minnesota Public Radio reported that he planned to resign, but his office put out a statement saying "not accurate."
"No final decision has been made and the Senator is still talking with his family," his office said.
Senate Minority Leader Chuck Schumer said, "I consider a Senator Franken a dear friend and greatly respect his accomplishments, but he has a higher obligation to his constituents and the Senate, and he should step down immediately."
Senator Kirsten Gillibrand said: "As elected officials, we should be held to the highest standards - not the lowest."
On Wednesday, Politico reported that a former Democratic congressional aide said Franken made an unwanted sexual advance at her doing his radio show in 2006 before he became a senator in 2009.
Franken denied the claim, saying that it was "categorically not true."
Later on Thursday, another woman, Tina Dupuy, a writer and commentator based in Manhattan, posted her account of being groped by Franken as they posed for a photo at a party during the 2009 inauguration of Barack Obama.
The woman's accusation came after a number of other women have alleged inappropriate conduct.
