Rep. Al Green (D-Texas) said he will bring articles of impeachment against President Trump in the next 30 days, telling protestors at an anti-Trump rally in Washington that he does not “deserve” to hold the executive office.

“We need a Senate that will convict him this time, and I want you to know, from my heart, from my heart, I understand that he is a Goliath. He is a Goliath. He has control of the generals in the military. He has control of the Justice Department. He has control of the Republican Party, but my friends, my friends, for every Goliath, there is a David,” Green said while addressing demonstrators at D.C.’s “Hands Off!” rally on Saturday.

“And I want you to know, Mr. President, this David is going to bring articles of impeachment against you within the next 30 days. Within the next 30 days, I’m bringing articles of impeachment. I’m coming for you. Mr. President, this David is coming for you,” the Texas Democrat said.

Green, who vowed to bring articles of impeachment against Trump roughly two months ago, argued that Trump does not “deserve the office” he holds.
