President Donald Trump and First Lady Melania Trump took some time away from their White House duties to attend the wedding of Treasury Secretary Steven Mnuchin and Scottish-born actress Louise Linton on Saturday. The newly married couple said their “I dos” in a lavish ceremony in Washington, D.C., partying the night away at a reception packed with family and friends. The wedding took place at the Mellon Auditorium, a historic government-owned public space that is connected to the Environmental Protection Agency’s headquarters and right around the block from the Trump International Hotel.
