At a dinner Friday, she said she wanted to "take Trump out"

Washington (CNN) Rep. Maxine Waters rejected Tuesday any suggestion that she was vowing to harm President Donald Trump last week when she said she would "take Trump out."

"That's absolutely ridiculous ... that a 79-year-old grandmother who is a congresswoman and who has been in Congress and politics all these years doing any harm," the California Democrat told CNN's Chris Cuomo in an interview on "New Day."
