Nancy Pelosi becomes second in line to the presidency after Mike Pence

Having successfully won re-election as House speaker on Thursday, Rep. Nancy Pelosi, D-Calif., is once again second in line to become president — at least on an interim basis — according to the rules of the presidential line of succession.

Pelosi, 78, in her second stint as speaker, now falls behind Vice President Mike Pence, 59, to take over if President Trump , 72, is unable to perform his duties as commander in chief. After Pelosi, rounding out the top five, are Sen. Chuck Grassley, R-Iowa, Secretary of State Mike Pompeo, and Treasury Secretary Steven Mnuchin.
