Gays stay with Bushes?

Here’s an excerpt from a Time interview with Laura Bush:

TIME: Have you ever had a gay couple stay with you in the White House or in Texas?

BUSH: I’m sure we have.

TIME: You wouldn’t have any objection?

BUSH: No, of course not.

This one is curious, I’m not sure if she’s lying. Anyone know if the Bushes have let a gay couple stay with them? Cheney’s daughter maybe?
