Donald Trump was very proud of himself — well, even more proud of himself than usual — Monday night for not bringing up Bill Clinton's marital "indiscretions" during his debate against Hillary Clinton. Trump bragged about not bringing it up on national television, while also seemingly ignoring the fact that he famously cheated on his wife, as well.

"But you want to know the truth? I was going to say something... extremely rough to Hillary, to her family, and I said to myself, 'I can’t do it. I just can’t do it. It’s inappropriate. It’s not nice,'" he said during the debate. Just days earlier, Trump tweeted that he had invited Gennifer Flowers, famous for having an affair with Bill Clinton, to the event in New York.

Following the debate, which many felt was won by Democratic nominee Clinton, Trump explained his remarks to a scrambling gaggle of reporters in the so-called "spin room." "Everything I wanted to say I got out except for the transgressions of Bill," Trump said to reporters, referring to Bill Clinton's cheating scandal during his White House administration. "I’m really happy I was able to hold back on the indiscretions in respect to Bill Clinton. Because I have a lot of respect for Chelsea Clinton."

In an interview with Fox right after the debate, Trump also talked about Bill Clinton's scandal and seemed to still be unsure if he'd bring it up in the next debate — even though, again, he kind of, sort of, already brought it up in the first debate.

On Tuesday morning, Trump appeared on the show Fox and Friends and again said that he was happy he didn't bring up the thing he was bringing up. "I was going to hit her with her husband’s women and I decided I shouldn’t do it because her daughter was in the room," Trump said. "I think I did the right thing."

He has also showed he's willing to bring it up in the next debate scheduled for Oct. 9, at Washington University in St. Louis, Missouri. "Maybe I'll tell you at the next debate. We'll see. But I'm very happy," he said in the spin room.

Trump, however, is not without sin when it comes to infidelity. He cheated on his first wife Ivana with Marla Maples, who went on to become his second wife. It was a story that served as endless fodder for the tabloids as the marriage fell apart. Trump and Ivana finalized their divorce in 1992. Trump and Maria Maples were married from 1993 to 1999. Their wedding came two months after she gave birth to their daughter.

Trump married Melania Knauss in 2005.

"After his second divorce and at other times when he was single, Trump was frequently seen out on the town with different women. He appeared on the cover of Playboy magazine, wrote in his books about all the women chasing him and publicly boasted about his sex life," the Chicago Tribune wrote.

Trump has said his cheating is different from Clinton's cheating because his marriage with Ivana "was over" when he began seeing Maples. But she tells a different story. She says she learned of the affair when she overheard her husband on the phone with Maples during a family Christmas trip in 1989.
