Treasury Secretary Steven Mnuchin, 54, married his 36-year-old fiancĂ©e Louise Linton on Saturday in front of a stunning list of Washington insiders and Wall Street elite.
It is Mnuchin's third marriage and Linton's second. Mnunchin, a former Goldman Sachs executive, met Linton, a Scottish actress, at a wedding in 2013, and the two got engaged in 2015.
