Republican presidential hopeful Mitt Romney is declining to weigh in on allegations of sexual harassment against rival Herman Cain.

Romney on Wednesday was asked about Cain during interviews. The former Massachusetts governor told Denver's KUSA that he only knows what he has seen on television and read in the newspapers.

He says questions about sexual harassment should be directed to Cain, not himself.

And he told Houston's KTRK that questions about candidates' personal lives are typically parts of campaigns and often keep some people from seeking public office. He was not asked specifically about Cain during that interview.

Cain has denied the allegations.
