The political feud between President Donald Trump and Sen. Ted Cruz of Texas during the 2016 election was one of the dirtiest in recent memory.

Trump and Cruz, who dropped out of the GOP primary in May 2016, attacked each other’s wives, citizenship, and integrity. They even threatened to sue, accusing each other of lying and cheating for various reasons.

After Trump won the party’s nomination, Cruz refused to endorse him at the Republican National Convention.

Cruz finally came around to make that endorsement in September 2016, and the two have worked together on Republican legislation since Trump took office.

By October 22, 2018, Trump even decided that Cruz was no longer "lyin' Ted" - his notorious nickname for the senator during the campaign - and was now "beautiful Ted." The president made the announcement ahead of a campaign rally he hosted in Texas to support Cruz's tough reelection bid.

Here are 40 of the most memorable attacks the two threw at each other during the 2016 presidential campaign:


Trump: "I don't think he's qualified to be president. Look at the way he's dealt with the Senate, where he goes in there — like, you know, frankly, like a little bit of a maniac. You're never going to get things done that way."

Cruz: "Listen, anytime someone is attacking your faith, that starts to suggest they're getting really nervous about what's happening in the race. I would be happy to invite Donald to come with me to church anytime he would like."

Cruz: "Unlike Donald, I didn't inherit millions of dollars. Instead, my dad came as an immigrant from Cuba with nothing, with $100 in his underwear. ... It is more than a little rich for Mr. Trump to make that accusation. You want to assess who stands with Wall Street? Then look at the actual records of the candidates."

Cruz: "I think in terms of a commander in chief, we ought to have someone who isn't springing out of bed to tweet in a frantic response to the latest polls. I think the American people is looking for a commander in chief who is stable and steady and a calm hand to keep this country safe."

Cruz: "Donald comes from New York and he embodies New York values." "Everyone understands that the values in New York City are socially liberal, are pro-abortion, are pro-gay-marriage, focused around money and the media."

Cruz: "Back in September, my friend Donald said he had his lawyer look at this from every which way and there was no issue there. There was nothing to this 'birther' issue. Since September, the Constitution hasn't changed. But the poll numbers have."

The next day, Trump declared: "I guess the bromance is over."

Trump: "He'll say whatever he wants to say. I actually think he's a very unstable person. I really believe that. I think he's a very unstable person. But I've never had somebody take something that you believe in and just say the exact opposite."

Cruz: "We need a commander in chief, not a Twitterer-in-chief. ... I don't know anyone who would be comfortable with someone who behaves this way having his finger on the button. I mean, we're liable to wake up one morning, and Donald, if he were president, would have nuked Denmark."

Trump: "This guy Ted Cruz is the single biggest liar I have ever dealt with in my life. I mean it. ... He will lie about anything. I've met much tougher people than Ted Cruz. He's like a baby. ... He's like a little baby. Soft, weak, little baby by comparison. But for lying, he's the best I've ever seen. ... A guy like Ted Cruz, he has no clue. He never employed anybody. He's a nasty, nasty guy."

Cruz: "Donald can't defend his own record. Whenever you point out what he's actually said, he just screams, 'liar.' He insults you. He attacks you. He makes it personal, and he gets very rattled. He doesn't like anyone pointing to his actual, substantive record. And I think that's a sign of weakness."

Trump: "The evangelicals didn't vote for him. And you know why? Because they don't like liars. They're really smart people. They don't want to vote for a liar. ... This guy Cruz lies more than any human being I've ever dealt with. He holds up the Bible and he lies."

Trump: "Ted Cruz, he's seriously — he's got a mental problem. Ted Cruz is a liar. He's got a problem, that he's a liar. I've never seen anybody [lie] to that extent."

Cruz responded civilly that night on Twitter but erupted to reporters the next day: "It's not easy to tick me off. I don't get angry often, but if you mess with my wife, if you mess with my kids, that will do it every time. Donald, you're a sniveling coward and leave Heidi the hell alone."

Trump: "Unlike Lyin' Ted Cruz I do not surround myself with political hacks and henchman and then pretend total innocence. Ted Cruz's problem with the National Enquirer is his and his alone, and while they were right about O.J. Simpson, John Edwards, and many others, I certainly hope they are not right about Lyin' Ted Cruz."

Cruz: "I'm not going to play that game. I'm not going to engage in insults, I'm not going to throw the mud. I don't really have any views on the size of any parts of Donald Trump's anatomy, and I'm not interested in talking about that."

Cruz: "Donald Trump is no different from politically correct leftist elites. Today, he joined them in calling for grown men to be allowed to use little girls’ public restrooms. As the dad of young daughters, I dread what this will mean for our daughters — and for our sisters and our wives."

Trump: "I have watched Lyin’ Ted become more and more unhinged as he is unable to react under the pressure and stress of losing, in all cases by landslides, the last six primary elections -- in fact, coming in last place in all but one of them. Today’s ridiculous outburst only proves what I have been saying for a long time, that Ted Cruz does not have the temperament to be President of the United States."
