Cantor and the McCain campaign wouldn't comment on the report, but the AP says a "Republican familiar with the conversations between Cantor and the McCain campaign said Cantor has been asked to turn over documents," though the source did not have specifics.
Cantor has been a strong McCain surrogate during the campaign, often offering harsh words about presumptive Democratic nominee Barack Obama. He is a pro-business representative from Virginia – a key swing-state and the home of potential Obama running mate Tim Kaine – though he is largely unknown outside the state.
Cantor, who is Jewish, has been a strong supporter of Israel. He is well liked by conservatives, a group McCain has had trouble shoring up.
