NEWARK - Geraldo Rivera says he's seriously thinking about running for U.S. Senate in New Jersey.
Rivera, who hosts a weekend show on Fox News Channel, said Thursday on his daily radio show on WABC-AM in New York that he's "truly contemplating" becoming a candidate. He says he has spoken to some people in the New Jersey GOP about a run.
Rivera asked his 30,000 Twitter followers how they feel about him challenging either Sen. Frank Lautenberg or Newark Mayor Cory Booker.
At 89, Lautenberg is the oldest sitting U.S. senator. The Democrat hasn't said if he will seek re-election.
Booker, also a Democrat, has announced he is exploring a run but hasn't made clear if he would challenge Lautenberg in a primary should he seek another term.
No Republican has formally announced an interest in running.
