ABC News’ Matthew Jaffe reports: In an appearance on "Fox News Sunday with Chris Wallace," possible vice presidential pick Sen. Evan Bayh, D-Ind., tried "not to make news" when asked if Sen. Barack Obama’s, D-Ill., presidential campaign has requested documents from him as part of a vetting process. "You know, that’s their business, Chris, and I think you should direct those questions to them," said Bayh. "I’m trying not to make news on that this morning, so I hope you’ll forgive me, but truly, they’ve established a process, it’s their process, and I think it’s up to them to…" Wallace then cut off the senator to press him on if he is part of this process. "You know, I’d love to answer your question but I think I really can’t," replied Bayh. As he has done before, Bayh said he would accept an offer to be Obama’s running mate, were he to be asked. "Well, I’ve said that’s not the sort of thing you’d say no to, Chris," Bayh said. "Which means you’d say yes?" asked Wallace. "Well, that’s the type of thing you do say yes to, and I’ve said that, but you should probably ask Joe, he has more experience with the vice presidential questions than I do," joked Bayh. Sen. John McCain, R-Ariz., supporter and former Democratic vice presidential candidate, Connecticut Independent Sen. Joe Lieberman appeared on the show alongside Bayh.
