Vice President Joe Biden and Republican vice presidential nominee Rep. Paul Ryan of Wisconsin participate in the vice presidential debate at Centre College, Thursday, Oct. 11, 2012, in Danville, Ky.

HUDSONVILLE, Mich. — Ann Romney says Republican Paul Ryan did "a great job" in his vice presidential debate against Democrat Joe Biden.

She said Ryan had a level head and was very smart. She said his character and integrity showed during Thursday's 90-minute debate.

Romney, the wife of GOP presidential nominee Mitt Romney, addressed a rally Friday morning in Hudsonville, Mich., near Grand Rapids. She said last night's debate showed why her husband chose the Wisconsin congressman to be his running mate.
