Sen. John Kennedy (R-La.) slammed "Late Show" host Stephen Colbert over his recent interview with former President Barack Obama. “ Late Show ” host Stephen Colbert and former President Barack Obama are such “best buds” that they should “get a motel room,” Republican Sen. John Kennedy (La.) said during a bizarre Fox News rant about their recent sit-down interview. Colbert announced last month that he would be interviewing Obama one last time before the curtains close for good on his CBS program.
