Delay’s camp is emphatic that the underlying story isn’t even true. From Roll Call:

Former House Clerk Jeff Trandahl says former House Majority Leader Tom DeLay (R-Texas) “had long sought to oust him from the job because he is openly gay,” according to a report in the Washington Blade.
Trandahl made the comments while speaking to a group of gays and lesbians aboard the ship Queen Mary II during a cross-Atlantic trip, according the Blade.
A spokeswoman for DeLay dismissed the charge that her boss wanted to sack (that is, fire) Trandahl. “We have no idea where this comes from, but it’s a very serious accusation and an outright lie,” she said.

And there’s this eminently plausible kicker:

A former GOP leadership staffer who served during DeLay and Trandahl’s tenure seemed surprised by Trandahl’s claim that DeLay wanted him fired, doubting that he was even aware the former Clerk was gay. “No member of Congress has a worse gaydar than Tom DeLay,” the former aide said.
