Tony Snow, former Fox News Sunday host and press secretary to President George W. Bush, has joined CNN as a conservative commentator, CNN/U.S. President Jon Klein said Monday.

Snow was to debut Monday night during "Larry King Live" after King's interview with Democratic presidential hopeful Sen. Hillary Clinton. He will be featured, along with a host of other political analysts, during CNN's coverage of Tuesday's Pennsylvania primary election.

This is a return appearance for Snow, who occasionally was the conservative co-host on CNN's "Crossfire." He stepped down as White House press secretary in September to pursue more lucrative work. He also is a survivor of colon cancer, although he said he left the White House post for financial, not health, reasons.

Separately, CNN started up an election Web site Monday. The site, League of First Time Voters, has basic information on each of the candidates and where they stand on particular national issues.

It also asks first-time voters to send videos on what is motivating them to vote in the 2008 general election.
