(Radio Iowa) — Western Iowa Congressman Steve King tweeted this (Friday) morning that if President Trump declares a state of emergency for border security, Trump should “build the whole wall out of concrete.” King said a concrete wall along the U-S/Mexico border would “stand forever as a monument to the Rule of Law.” King went on the house floor early in his congressional career with his own model for a “fence and a wall” along the southern border. King’s model called for “precast concrete panels 10 feet wide and 13 feet high.”

Two Republicans have announced this week they intend to challenge King in a Republican Primary if King runs again in 2020. Also this week, King has been rebuked by House G-O-P leaders for comments he made to The New York Times about “white supremacy, white nationalism and Western Civilization.” King issued a written statement yesterday (Thursday) afternoon, saying he is “simply a Nationalist.”
