Sen. Roy Blunt (R-Mo.) will spearhead a movement to stir up support for Republican presidential candidate Mitt Romney in Congress, Romney’s campaign announced Tuesday.

“It is an honor to have Roy’s support,” Romney said in a statement that also called that Blunt an “effective liaison in sharing my vision for America with his colleagues in both the House and the Senate.”

Blunt, then a member of Congress, filled a similar role for George W. Bush’s campaign in 2000.

Romney is looking to drum up more congressional support in advance of the Republican primary. Romney currently leads the field in House endorsements, but the number of members who have endorsed any candidate is much lower this cycle compared to this point in the 2008 campaign.

Romney’s biggest endorsements so far include Sens. Orrin Hatch (R-Utah) and Scott Brown (R-Mass.), House Armed Services Committee Chairman Buck McKeon (R-Calif.), and a widely-touted endorsement last week by former GOP candidate Tim Pawlenty.

“Our nation faces historic challenges today, and under President Obama’s policies, we’ve witnessed high unemployment, skyrocketing debt, out-of-control spending, and burdensome regulations that have stifled job creation,” Blunt said in a statement released by Romney’s office. “Through his experience in the private sector and as governor, I believe Mitt has the right background to help create more economic certainty and spur job growth in Missouri and nationwide, and that’s why I’m proud to lead his Congressional Team."
