Many compared Foley's conspicuous spot at the Trump rally to the similarly prominent seat Orlando terrorist Omar Mateen's father had two nights earlier at a Hillary Clinton rally in Kissimmee, Florida.
"To be compared to Mateen's father in some way is just an amazing stretch," Foley said. "I got a kick out of some of the commentary. But it comes with the territory."
The Clinton campaign said it didn't know Seddique Mateen attended Tuesday's rally. Trump's campaign didn't immediately respond to an inquiry about Foley's appearance.
At Wednesday's rally, Trump scoffed at the Clinton camp's Mateen explanation, turning to Foley and the others seated behind him as he made his point.
"When you get those seats, you sort of know the campaign. So when she says, "We didn’t know," … They knew," Trump said.
Foley said Trump is a "very gracious" friend who "welcomed me back to Mar-a-Lago after I had my fall from grace."
"I was very disappointed in myself, and I was sad to have let my constituents down," Foley said of the 2006 scandal. "I made a mistake and I paid dearly for it, (but) I have every right to attend political events."
Foley said neither Trump nor his campaign knew in advance that he was attending the rally with the group of Florida Republicans.
