President George W. Bush commented on Sen. Hillary Clinton’s controversial “red phone” campaign ads at the White House today, telling reporters, “When that red phone rings, I just let it go straight to voice mail.”

In a rebuke of Clinton, President Bush added, “If she doesn’t know about letting your calls go straight to voice mail, I don’t think she has the experience to be president.”

Campaigning in Pittsburgh, former President Bill Clinton took issue with Bush’s remarks, telling reporters, “When I get a call at 3 a.m., I always pick up, if you know what I mean.”

Shortly after making his remarks, the Clinton campaign said that it was revising the former president’s itinerary to focus on states that had already voted in February.

Elsewhere, Sen. John McCain released a new series of campaign ads, showing him answering a telegraph key at 3 a.m.
