The attempted attacks on former President Barack Obama and Bill and Hillary Clinton were “despicable” acts, the White House announced Wednesday after suspicious packages were intercepted by the Secret Service.

“These terrorizing acts are despicable, and anyone responsible will be held accountable to the fullest extent of the law,” White House press secretary Sarah Sanders said in a statement. “The United States Secret Service and other law enforcement agencies are investigating and will take all appropriate actions to protect anyone threatened by these cowards.”
