Sen. Orrin Hatch (R-Utah) on Tuesday highlighted on Twitter the members of the House's GOP transition team who hail from Utah.

"Congrats to @jasoninthehouse and Rep. Rob Bishop for being on the GOP Transition Team for new house members. They'll do a great job," he tweeted.

Jason Chaffetz's status as an up-and-comer in the House might not ultimately bode well for Hatch, who could be vulnerable to a challenge from the right in 2013. Chaffetz has already said he's considering a run for Hatch's seat. 

"I see no point or reason to take my hat out of that arena," he told The Washington Post in late October, adding that he'll wait until 2011 to officially decide.
