From the White House pool report:
President Trump and the First Lady arrived at the Mellon Auditorium in DC at 6:32 after the short half mile minute ride just a couple blocks down Constitution Avenue – past crowds of onlookers snapping pics.
They are attending the wedding of Treasury Secretary Steven Mnuchin and the Scottish actress Louise Linton. Vice President Pence is also scheduled to be here.
Pool got a very quick glimpse from a distance of POTUS in a black tie tuxedo and Melania Trump in a pink blush dress.
Here’s what we know about FLOTUS’s ensemble, per her spokeswoman Stephanie Grisham: “She will be wearing a Gilles Mendel silk chiffon gown with Manolo Blahnik pumps.”
The wedding is taking place at the Mellon Auditorium, a historic government-owned public space that is connected to the US Environmental Protection Agency’s headquarters and right around the block from the Trump International Hotel. The auditorium has hosted a variety of big events over the years: FDR re-launched the mandatory military draft here in 1940; Harry S. Truman signed the North Atlantic Treaty establishing NATO here in 1949; Bill Clinton signed NAFTA here in 1993. It was also the set for ‘West Wing,’ ‘Transformers’ and ‘Top Chef.’
The president spent more than four hours at the wedding, returning to the White House close to 11:00 pm ET.
