Rep. Jamie Raskin on Sunday described balancing the trauma of his son’s recent death by suicide with the horror of the US Capitol riot and his duty as lead impeachment manager against President Trump.

“I’m not going to lose my son at the end of 2020, and lose my country and my republic in 2021,” the Maryland Democrat vowed in an appearance on CNN’s “State of the Union.”

“It’s not going to happen.”

Raskin’s 25-year-old son, Thomas, took his own life on Dec. 31, following a long battle with depression.

“He had overwhelming love for humanity and for our country in his heart, and really for all the people of the world,” Raskin said, describing “a life that dazzled.”

Raskin remembered his son, a second-year student at Harvard Law School, as a talented slam poet dedicated to human rights and animal welfare.

The lawmaker said that he carries his son’s memory with him, and that he feels him “in my chest” — including on Jan. 6, when a mob of Trump supporters stormed the Capitol in an attempt to prevent the certification of Joe Biden’s election win.

“I felt my son with me,” said Raskin, who was joined that day on Capitol Hill by his youngest daughter and his son-in-law.

They “got caught in a room off of the House floor, and between them and me was a rampaging armed mob that could have killed them easily, and was banging on the doors where they were hiding under a desk with my chief of staff,” said Raskin.

The invasion saw five people die, among them a Capitol Police officer who was pepper-sprayed and bludgeoned to death with a fire extinguisher.

Raskin said that his son is also with him in spirit as he proceeds as the lead lawmaker tapped by House Speaker Nancy Pelosi in impeaching Trump on charges of inciting that very riot.

“First of all, I don’t know if you’ve ever tried to say ‘no’ to Speaker Pelosi about anything,” cracked Raskin when describing why he agreed to shoulder the burden. “But she’s actually been very sensitive and thoughtful. She wanted me to do it, because she knows that I’ve devoted my life to the Constitution and to the republic.

“But I did it really with my son in my heart, helping lead the way.”
