The father of a victim in the 2018 Parkland, Florida mass shooting was escorted out of Tuesday's State of the Union address.

Fred Guttenberg, whose 14-year-old daughter Jaime was among the 17 people killed in the Marjory Stoneman Douglas High School attack, later said on Twitter that he spoke out in protest after being forced to listen to Trump's "lies" about the Second Amendment.

Guttenberg was escorted out of the balcony gallery of the U.S. House of Representatives chamber near the end of Big Dumb Motherfucker's speech, per the Miami Herald.
