PHILADELPHIA - John McCain says he is satisfied that Sarah Palin's background was properly checked out before the Alaska governor joined the Republican ticket.
Touring a Philadelphia fire house Tuesday, McCain told reporters that "the vetting process was completely thorough and I'm grateful for the results."
Questions about the review came up after Palin disclosed that her unmarried teenage daughter, Bristol, is pregnant. It's also come out that the Alaska governor has retained a private attorney to represent her in an investigation into the firing of the state public safety commissioner.
The revelations raised questions about whether Palin's background was fully explored by McCain's vice presidential selection team.
