Video from Rep. Elijah Cummings' memorial service last week shows a pallbearer passing over Senate Majority Leader Mitch McConnell in a handshake line.

A clip of the incident went viral on Twitter, with several people laughing at McConnell's apparently shocked expression.

The pallbearer, Bobby Rankin, a close personal friend of Cummings', said he blames McConnell for standing in the way of his deceased brother's access to veterans' healthcare.

On Thursday, Cummings became the first black lawmaker to lie in state at the US Capitol, and numerous former colleagues eulogized him.

A pallbearer at Rep. Elijah Cummings' memorial service in the US Capitol on Thursday went viral online after skipping over Senate Majority Leader Mitch McConnell in a handshake line.

A video clip posted on Twitter showed C-SPAN's footage of the line where speakers and pallbearers shook hands with several lawmakers, including House Minority Leader Kevin McCarthy, Senate Minority Leader Chuck Schumer, McConnell, and House Speaker Nancy Pelosi.

The man can be seen making his way down the line of lawmakers, grasping McCarthy's hand, then Schumer's, and then swiftly moving past McConnell before stopping in front of Pelosi and shaking her hand.

The pallbearer, Bobby Rankin, a close personal friend of Cummings, didn't know footage of the moment had gone viral until a Washington Post reporter contacted him to ask about it.

Rankin told Tthe Post that he couldn't bear to shake McConnell's hand because he blames the powerful Republican for standing in the way of his deceased brother's access to healthcare.

Rankin's brother, Jerry, died last year of multiple myeloma after prolonged exposure to contaminated water while serving in the Marines at North Carolina's Camp Lejeune. The form of cancer is linked to the Marine base's three decades of water contamination. Rankin said his brother was denied the veterans healthcare he was entitled to.

"When I saw Mitch McConnell, all I saw was my brother's face," Rankin told The Post.

Rankin said Cummings tried to secure Jerry's benefits and "reached across party lines" to McConnell, among other Republicans.

"I could not put my hands in the man's hand who refused to help somebody who served his country," Rankin said, adding, "I couldn't do it, because I was thinking about my brother."

McConnell, who had been reaching for the pallbearer's hand, dropped his arm and appeared stricken in the seconds after Rankin passed him by.

The Kentucky Republican turned and looked at Schumer in apparent disbelief.

Cummings, who represented Maryland's 7th Congressional District, died on October 17. He was 68.

He became the first black lawmaker to lie in state in the Capitol and was eulogized by several former colleagues — including McConnell — on Thursday.

In his remarks, McConnell praised Cummings' work quelling violence in Baltimore during protests in 2015 over the death of Freddie Gray, a black man who died in police custody.

"'Let's go home. Let's all go home,'" McConnell recalled Cummings saying. "Now our distinguished colleague truly has gone home."
