ATLANTA – Former Republican presidential candidate Herman Cain is set to announce he is endorsing former Speaker of the House and fellow Georgian Newt Gingrich for the Republican presidential nomination, a source tells MyFoxAtlanta.com.

The source says Cain is preparing to make the announcement Monday, but the details of the formal announcement are still being worked out.

Gingrich's campaign also says Gingrich will hold a press conference at 2:00 p.m. Monday afternoon in New York, following a meeting with Donald Trump.

Cain announced Saturday that he was suspending his campaign for the White House after coming under continuing scrutiny amid allegations of sexual harassment and an affair.

"These false and unproved allegations continue to be spinned in the media and in the court of public opinion so as to create a cloud of doubt over me and this campaign and my family," he told supporters in Atlanta.

Other Republican candidates have been scrambling to woo his supporters to their cause following the news.

Gingrich told reporters he had held a private conversation with Cain on Saturday and he later released a statement calling him a "powerful voice in the conservative movement" who "elevated the dialogue of the Republican presidential primary"...
