Shouting protesters repeatedly interrupted the rally, including a moment of silence for victims of a shooting in a synagogue in Pittsburgh on Saturday that left 11 people dead.
Sen. Lindsey Graham (R-S.C.) said in a tweet on Monday that the only people yelling at him are those who want to turn the U.S. into a "mob."
"All the people wanting to yell at me would turn the country into a mob ... they don't respect the presumption of innocence," Graham tweeted.
"They have a view of the government that would make us Venezuela."
