President Trump and his wife Melania on Saturday attended the wedding of Treasury Secretary Steven Mnuchin Louise Linton in Washington, D.C.

The Trumps arrived in the early evening. The president wore a black tie tuxedo and Melania was adorned in a pink blush dress, a pool report said.

"She will be wearing a Gilles Mendel silk chiffon gown with Manolo Blahnik pumps," Melania's spokeswoman, Stephanie Grisham, had said.

Mnuchin met Linton in 2013 and the two have been engaged since 2015. She is a Scottish actress and has been married once before, while he is a former Goldman Sachs executive who has been married twice before.

Earlier this week, Commerce Secretary Wilbur Ross, a close friend of the couple, accidentally revealed the wedding would be taking place during a conference in Washington, D.C., the Washington Post reported.

The wedding venue is Mellon Auditorium, which is connected to the Environmental Protection Agency's headquarters, and is around the block from the Trump International Hotel, the pool report noted.

NBC's Kelly O'Donnell tweeted out that White House press secretary Sean Spicer was in attendance. Vice President Mike Pence is also scheduled to attend the event, the pool report said.
