Cory Booker, a Democrat from New Jersey, died Sunday of complications from pneumonia at his home in Newark, N.J. The Booker family confirmed the death.
Booker, 53, was diagnosed with pneumonia on Sept. 17 and underwent several surgeries and tests to try to cure it.
He was released from a New Jersey hospital on Sept 20, but was still recovering at home.
Booker and his wife, Jocelyn, are expecting their first child, a daughter, the Associated Press reported.
Booker’s wife, the former New York City mayor, is the daughter of former President Bill Clinton.
The New York Times reported that Booker had been working on his book about the Booker family and was in negotiations to do a TV movie about the senator.
“Cory is in a critical period, but the time for that to happen is now,” his brother, Rep. John Conyers, D-Mich., told the AP.
“He’s going to make a great senator for a long time.”
Bookers death comes after the death of Sen. Elizabeth Warren, D, Mass., and a number of other senators.
A spokesman for Warren, Sen. Patty Murray, D of Washington, said in a statement that “the Booker family is deeply saddened by Cory’s passing.”
“Cyrus was a man of principle and integrity, and his work as an elected official and advocate has been a driving force behind the bipartisan progress we have seen in Washington,” Murray said.
“We will remember him as a man who fought tirelessly for the most vulnerable in our country, who served and sacrificed for us all, and who stood up for the rights of women and girls.”
