US Rep. Eric Cantor of Virginia has been asked for "personal documents" by John McCain's campaign. That comes from a Republican with close knowledge of conversations between Cantor and the McCain presidential campaign. Cantor, 45, who is Jewish, is the chief deputy minority whip in the House. He has been mentioned among several Republicans as a possible running mate for McCain, the presumptive Republican presidential nominee. The Republican said Cantor has been asked to turn over documents, but did not know specifically what records were sought. The person spoke on the condition of anonymity because neither the McCain campaign nor Cantor's office wishes to discuss the running mate selection process.
