Donald Trump's rival Thomas Massie has hit back after the commander-in-chief launched a blistering attack on his recent marriage.

The president penned an astonishingly personal assault against Massie, 54, and his 36-year-old wife Carolyn Grace Moffa on Friday amid the Kentucky Republican's campaign to release documents related to pedophile Jeffrey Epstein's crimes.   

'Did Thomas Massie, sometimes referred to as Rand Paul Jr., because of the fact that he always votes against the Republican Party, get married already??? Boy, that was quick!' wrote Trump, who himself has been married three times.

'No wonder the Polls have him at less than an 8% chance of winning the Election,' he added. 'Anyway, have a great life Thomas and (?). His wife will soon find out that she’s stuck with a LOSER!'

His comments came less than two weeks after Massie and Moffa married in Pennsylvania, a ceremony held just one year after Massie lost his wife, Rhonda - the mother of their four children. 

When asked about the attack on ABC's This Week, Massie said he was not concerned as he joked that his new bride told him: 'I told you we should have invited Donald Trump. He's mad that he didn't get an invitation.'

'We're taking it with a grain of salt,' Massie continued. 'He's being a bully or trying to be a bully.'

The congressman also dismissed Trump's newfound support for the former Navy SEAL that is gearing up to challenge him in the 2026 midterm elections.

He noted that those funding Ed Gallrein's campaign are three billionaires, whom he accused of having connections with Epstein.

'Dogs don't bark at parked cars,' Massie declared to ABC's Jonathan Karl on Sunday. 

'And we are winning. I am not tired of winning yet,' he continued, borrowing one of the president's favorite phrases as he spoke about the 23,000 damning documents released by the House Oversight Committee on Wednesday.

'Not only the speaker, the attorney general, the FBI director, the president himself and the vice president, they are taking a big loss this week because after months of fighting, I am winning this week.'

Massie then advised his 'Republican colleagues who are deciding how to vote' that Trump 'can protect you in red districts right now by giving you an endorsement, but in 2030, he's not gonna be the president and you will have voted to protect pedophiles if you don't release these files.'

'The record of this vote will last longer than Trump's presidency,' he noted. 

Massie has previously claimed that the Trump administration is resisting the release of the so-called Epstein files to shield the president's allies from embarrassment.

'They'll claim privately they're trying to avoid embarrassment for some of the president's friends. And they'll say that privately. They won't say that publicly,' Massie said in a Friday interview with a Cincinnati radio station, as reported by Newsweek.

'But I don't think embarrassment is a good reason, like saving somebody from embarrassment is a good reason to protect dozens of men who preyed on underage women in a sex trafficking operation,' he added. 

Massie's remarks on Sunday came as Marjorie Taylor Greene also slammed the president amid her viral rift with Trump over the release of the Epstein files.

In an interview with CNN's State of the Union, the one-time Trump ally scorned the president for recently welcoming Syrian President Ahmed al-Sharaa to the White House.

The Saudi-born leader joined al-Qaeda in Iraq just before the US invasion in 2003. He was captured by American forces and imprisoned for five years until 2011 - and there has been a $10 million bounty on his head since.

Greene referenced the leader's terrorism ties in the interview, saying that Trump's actions were a disgrace and slap in the face to the thousands of veterans who have fought in the Middle East. 

'I think that was very hurtful to the great men and women who served over in the Middle East and were sent there, and many of them that were killed and injured and live with PTSD to this day, from fighting al Qaeda,' the Georgia congresswoman said.

She stopped short of calling herself more 'America First' than Trump when prompted to do so by Bash, but she did note that 'promoting H1B visas to replace American jobs, bringing in 600,000 Chinese students to replace American students...  are not America first positions.'

In the wide-ranging interview, which lasted about 20 minutes, Greene also doubled down on her push to release the Department of Justice's files relating to financier and convicted pedophile Jeffrey Epstein, who was a known associate of top government, media, and business leaders both in the United States and the United Kingdom.

However, she maintained that nothing in the files would be damaging to Trump, per the female victims that she has spoken to and given a platform to share their stories. 

'I stand with these women. I stand with rape victims, I stand with children who are in terrible sex abuse situations, and I stand with survivors of trafficking and those that are trapped in sex trafficking', Greene told Dana Bash, adding that she would keep playing her 'small part' for the files to be released because 'rich and powerful people' should not be protected if they have done anything wrong.
