The Associated Press and National Review report the candidate has told staff that new allegations about an affair (which he denies) have taken a toll on his family.

Republican presidential candidate Herman Cain is "reassessing" his campaign but still plans to move ahead at this time, his Iowa campaign director tells The Associated Press.

According to the wire service, that Iowa campaign aide, Steve Grubbs, said that Cain told senior staff today during a conference call that new allegations from a woman who claims to have had a long affair with him have taken an emotional toll on his family. Cain also said the allegations — which he denies — have damaged his fundraising, Grubbs told the AP.

Earlier, National Review's The Corner blog cast a slightly different take on the news. It wrote that "in a conference call this morning, Herman Cain told his senior staff that he is 'reassessing' whether to remain in the race. He told them he will make his final decision 'over the next several days.' "

Cain's campaign, as we've reported, had earlier been rocked by allegations that he sexually harassed women while he was at the helm of the National Restaurant Association. He denies those allegations as well. [Copyright 2011 National Public Radio]
