(CNN) - The two senators widely believed to be at the top of Barack Obama's shortlist for VP have been given prime-time speaking slots at the Democratic convention Wednesday night - the very same night the vice presidential candidate is slated to speak.
According to the Democratic National Convention Committee, both Indiana Sen. Evan Bayh and Delaware Sen. Joe Biden will deliver speeches on national security during the marquee night - the same evening former President Bill Clinton is also scheduled to speak.
New Mexico Gov. Bill Richardson, West Virginia Sen. Jay Rockefeller, Senate Majority Leader Harry Reid, and Colorado Sen. Ken Salazar will also speak Wednesday evening, according to the convention committee.
But Biden and Bayh's appearance especially is sure to heighten speculation one of the two senators will ultimately be named Obama's running mate. The announcement also comes the same day Biden hit the campaign trail for the Illinois senator, accepting an endorsement on his behalf from the International Association of Firefighters in Las Vegas.
