House Speaker Mike Johnson has warned fellow lawmakers ahead of Israeli Prime Minister Benjamin Netanyahu’s address to Congress on Wednesday that anyone who tries to disrupt the speech will be subject to arrest.

In a letter, Johnson said that extra sergeants-at-arms and Capitol Police would be on hand to deal with any disruptions, noting he has adopted a “zero-tolerance” position from lawmakers and any guests they bring.

“If any disturbance does occur, the Sergeant at Arms and Capitol Police will remove the offending visitor(s) from the gallery and subject them to arrest,” Johnson wrote.

If any lawmakers are involved in disruptions, they will be asked to cease and desist by the sergeant-at-arms.
