Christopher Dingell remembers his father, the longest serving congressman in history

As word spread of former Michigan congressman John Dingell's death, those who were close to him took a step back at his life and the legacy he leaves behind.

"He believed in an America that had room for everyone of us," said his son, Christopher Dingell.

An advocate of the environment and a proponent of health care, one of his final acts in congress was passing the Affordable Care Act. From World War 2 to Twitter funny-man, his son said he continues to hear of ways his dad impacted others.

"Everywhere I go, I run into people have dealt with my father." he said.

In an acknowledgement of his legacy, President Trump had flags lowered to half-staff. 

Funeral services have already been planned for Dingell. Visitation will be from 11 a.m. to 8 p.m. on Monday, Feb. 11 at the Ford Community and Performing Arts Center. The funeral is planned for 11 a.m. on Tuesday, Feb. 12 at the Church of the Divine Child.

Following Tuesday's service, Dingell's casket will be flown to the capital, where it will be driven past the United States Capitol on the East Plaza. He will be buried in Arlington Cemetary.
