Rep. Emanuel Cleaver (D-Mo.) warned Sen. Claire McCaskill (D-Mo.) of “disloyalty” to President Obama if she should seek to distance herself from the White House in her re-election campaign.

Cleaver, who’s seen as the likely next leader of the Congressional Black Caucus (CBC), cautioned the centrist senator of distancing herself from Obama, the way many endangered incumbents had done in the closing weeks of the 2012 election.

“Any attempt to extricate herself from him will be an act of disloyalty,” Cleaver told McClatchy in a piece profiling McCaskill’s re-election campaign. “She will not do that at all.”
