Lawrence O'Donnell host is taking a leave of absence from his show following his mother's death on Sunday.
MSNBC host Chris Hayes will fill in for O'Donnell. Hayes announced the news on the program on Monday night. He said, "The most devoted fan of this show is not watching tonight. Lawrence's mother, Frances O'Donnell, died Sunday morning in her home surrounded by her children and grandchildren. Mrs. O'Donnell was 93."
Frances O’Donnell was the office manager for the family's law firm in Boston, according to the Hollywood Reporter. The firm won a historic civil rights case about the 1975 shooting death of a black man by Boston police, which was the subject of Lawrence O'Donnell's book Deadly Force.
