Michael Steele said Friday that he has made mistakes as chairman of the Republican National Committee (RNC).

During an appearance on Sean Hannity's show on the Fox News Channel, Steele said, "I'm trying to do the best I can as national chairman. I've made mistakes..."

Steele also defended himself, saying, "I've got three victories under my belt: New Jersey, Massachusetts and Virginia," referencing the two 2009 governor races and Sen. Scott Brown's (R-Mass.) win in January.

He added, "Look, this is the bottom line: I stay focused very much on winning in November. I'm going to work very hard to make sure more Republicans, more good, fiscal conservatives get into the Senate, into Congress, into the governorships, into the state legislatures this November."

Steele has been made a series of gaffes since taking over at the RNC. He has also attracted criticism from GOP officials on how the RNC has spent some of its money in the 2010 cycle.
