Former Massachusetts Gov. Mitt Romney (R) is keeping a quiet public schedule as he works to organize another run for president in 2012.

He has no public events scheduled next week, according to his political action committee (PAC). The only thing on his public calendar at this point is an appearance in New Hampshire at the end of April, for a summit hosted by Americans for Prosperity. The meeting will be attended by other GOP presidential hopefuls.

Romney is working behind the scenes, meanwhile, to build support for his campaign. He sent a total of $45,000 from his PAC to the three Republican campaign committees in Washington. Rep. Paul Ryan (R-Wis.), who put together the Republicans' 2012 budget proposal, also told Time magazine that Romney called him this week, though the two didn't connect.
