 The debate is less than a day away. I'm Carmen Roberts, Fox News. President Biden is still prepping for Thursday night's CNN debate with former President Trump. It has been six days now since we've seen the president hunkered down at Camp David with a pretty long list of advisers. His former chief of staff, Ron Klain, is reportedly playing a leading role in those mock debates, which are happening at an airplane hangar and movie theater that's been converted to a stage. Others from Biden's inner circle include Mike Donilon and Anita Dunn.
