A federal judge sentenced Cesar Sayoc, the so-called MAGA bomber, to 20 years in prison Monday.

Sayoc, 57, pleaded guilty earlier this year to a spate of threatening pipe bombs that he sent to prominent Democrats across the country in the fall of 2018. Prosecutors charged Sayoc in October with sending 16 improvised explosive devices to former President Barack Obama; former Vice President Joe Biden; former Secretary of State Hillary Clinton; former Attorney General Eric Holder; Sens. Cory Booker of New Jersey, and Kamala Harris of California; billionaire activist George Soros; former CIA Director John Brennan via CNN headquarters, and others.
