After 12 years of marriage and less than two years into his congressional career,  Georgia Republican Rep. Rich McCormick has filed for divorce from his oncologist wife Dr. Debra Miller. 

The case was filed by McCormick on May 3. A mutual restraining order was also filed, DailyMail.com exclusively reports. 

McCormick, 55, and Miller, his second wife, share seven children and live in Suwanee, Georgia. When approached about the reasoning for the divorce, Miller texted DailyMail.com: 'I'm sure that he will not be forthcoming.' 

Capitol Hill insiders say McCormick has often been seen acting overly friendly toward a female Republican member of the House Beth Van Duyne, R-Texas.  

One GOP member told DailyMail.com they had seen McCormick and and Van Duyne, 53, 'holding hands under the table' at the weekly Republican Study Committee lunch within the last three to four months and had seen him 'grab the small of her back' on the House floor during votes. 

Two eyewitnesses say they have seen he and Beth holding hands, with one witnessing it as the pair were leaving votes.

And during the State of the Union on March 7, the two could be seen sitting and laughing together while watching Biden's speech.

McCormick even reached over to gently squeeze Van Duyne's arm in a tender moment between the pair captured on camera. 

Asked if the divorce involved an alleged affair he may have had with a colleague, his soon-to-be ex-wife Miller replied: 'You should ask Rich and his colleague.' 

A third witness told DailyMail.com they had seen Van Duyne holding on to the arm of McCormick while walking out of the Longworth Office building late at night. 

Van Duyne has been divorced from her former husband of 17 years since 2012. They share two children.

Asked about the cozy behavior and the divorce, a McCormick spokesperson told DailyMail.com: 'Congressman McCormick and Dr. Miller have been separated for quite some time. He has kept that private and will continue to keep his personal life out of the media spotlight.'

A representative for Van Duyne declined to provide comment to DailyMail.com. 

McCormick and his wife were pictured together as recently as over the Christmas holiday. But he notably did not include her in a recent Mother's Day tribute on X.

McCormick's Facebook account says the pair were married on August 16, 2011. 

McCormick spent over 20 years as a pilot in both the Marine Corps and the Navy and was also an emergency room physician in Georgia's Gwinnett Medical Center. 

He is in his first term in Congress, having joined in January 2023. He ran unsuccessfully for the Georgia's 7th District in 2020 against Democrat Carolyn Bordeaux. 

In November McCormick was the lead author of a censure resolution for Rep. Rashida Tlaib, D-Mich., for "promoting false narratives regarding the October 7, 2023 Hamas attack on Israel and for calling for the destruction of the state of Israel.' 

Van Duyne is a Republican congresswoman from Texas

Happy Mother's Day to all the incredible moms out there! Today, I want to give a special shoutout to my own mom. As a single mother, she showed me the true meaning of hard work and determination.

She taught me to never settle for mediocrity and to always strive for greatness.… pic.twitter.com/CMopcxlevM

Shortly after that, Rep. Marjorie Taylor Greene, R-Ga., who had also introduced a Tlaib censure that was not successful, accused McCormick of getting physically aggressive with her. 

Sources told CNN that in a private meeting with House Speaker Mike Johnson in December, Greene claimed her male colleague 'grabbed her by the shoulders and shook her' and asked the Speaker to address the issue.

'I understand why there would be a lot of raw emotions following the censure vote given that her censure was tabled and mine passed. My intention was to encourage Rep. Greene by making a friendly gesture,' said McCormick. 

He denied getting physically aggressive with her.
