President Donald Trump took to Twitter on Monday afternoon to respond to Democratic Rep. Maxine Waters' call to harass Trump administration officials in public, calling the California representative "an extraordinarily low IQ person."

"Congresswoman Maxine Waters, an extraordinarily low IQ person, has become, together with Nancy Pelosi, the Face of the Democrat Party," Trump tweeted. "She has just called for harm to supporters, of which there are many, of the Make America Great Again movement. Be careful what you wish for Max!"

Trump's tweet comes one day after Waters encouraged her supporters to mob and harass people who are associated with the president in public.

"You have members of your Cabinet that have been booed out of restaurants, who have protesters taking up at their house who say, 'No peace, no sleep,'" Waters said at a rally on Sunday, adding, "God is on our side."

She later said: "If you see anybody from that Cabinet in a restaurant, in a department store, at a gasoline station, you get out and you create a crowd and you push back on them, and you tell them they're not welcome anymore, anywhere."

The debate over treatment towards members of the Trump administration in public ignited over the weekend after White House press secretary Sarah Huckabee Sanders was kicked out of a Lexington, Virginia, restaurant after one of the establishment's owners told her she was part of an "inhumane and unethical" organization.
