Rep. Todd Akin (R-Mo.) did not show up for his scheduled interview with Piers Morgan on his show Monday night, prompting Morgan to call him a "gutless little twerp."
His absence will certainly increase the speculation over when or whether the lawmaker will bow to mounting pressure to exit the U.S. Senate race in Missouri against incumbent Sen. Claire McCaskill (D).
But Akin persisted, tweeting out his plans to remain the Republican nominee for Senate in Missouri and going on Sean Hannity's radio show to reaffirm his commitment. His appearance on Morgan's show was expected to shed further light on his decision, or perhaps offer a national platform for a withdrawal.
