Actor Robert De Niro sounded off on the sentencing of “MAGA bomber” Cesar Sayoc outside a Manhattan courthouse on Wednesday.

Sayoc pleaded guilty to sending 16 rudimentary bombs to targets including Hillary Clinton, former Vice President Joe Biden, several Democratic members of Congress, former President Barack Obama, billionaire George Soros and De Niro himself. Devices were also mailed to CNN offices in New York and Atlanta, with former Obama administration intelligence bosses as the intended recipients.

“I hope people realize, this fool, he’s a danger,” De Niro told reporters on Wednesday (via The New York Post).

Prosecutors had called for a life prison sentence for Sayoc, saying the sentence is “necessary and appropriate.” Sayoc’s lawyers had argued that a decade in prison was enough. Sayoc ultimately received 20 years behind bars for his actions.

Federal authorities took Cesar Sayoc into custody on Oct. 26, 2018 in Florida in connection with the mail-bomb scare that earlier widened to 12 suspicious packages. (Broward County Sheriff's Office via AP)

De Niro seems to take issue with the 20-year sentence being lighter than what prosecutors were hoping for. The one-time pizza delivery man faced a mandatory decade in prison after pleading guilty to explosives charges on March 22 for mailing 16 inoperative pipe bombs days before the midterm elections last fall.

De Niro made his comments outside a Manhattan civil court where he appeared as part of his divorce proceedings from wife of more than 20 years, Grace Hightower. According to The Post, the actor is arguing that his 2004 prenup covers Hightower with a reported $6 million apartment, $500,000 cash and $1 million a year in alimony. However, she allegedly argues she is entitled to half his half-billion-dollar fortune.
