Utah congressman endorses Romney

From NBC's Mark Murray and Domenico Montanaro

Rep. Chris Cannon (R-UT) endorsed Romney today. Per the campaign, Cannon will also join a "Congressional Whip Team" led by Reps. Jim McCrery (R-LA), Dave Camp (R-MI) and Buck McKeon (R-CA).

Since the topic of immigration is back in the news -- after Tuesday's Democratic debate and Romney upping the ante on the issue -- we wonder if Cannon's past support for comprehensive immigration reform will be something his rivals (especially Thompson) draw attention to.
