AP Sources: Ryan Expected To Endorse Romney

The House Budget Committee chairman, Paul Ryan of Wisconsin, is expected to endorse Republican presidential hopeful Mitt Romney.

Two Republican officials told The Associated Press that Ryan’s endorsement could come as soon as Friday, when Romney is scheduled to give an economic speech in Appleton, Wis. The officials spoke on condition of anonymity because they were not authorized to speak publicly.

Wisconsin’s Republican primary is Tuesday.

Ryan is the author of the House Republican budget that proposes to slash federal spending and shrink government. While the plan is doomed in the Democratic-controlled Senate, it sets out the GOP’s fiscal policy.

Romney has praised Ryan’s effort to cut taxes and overhaul the tax code.

Ryan has downplayed speculation that he could be picked as the Republican vice presidential candidate.
