Barack Obama, Chuck Schumer, Elizabeth Warren and more thank House Speaker Nancy Pelosi for her service

U.S. political leaders are thanking House Speaker Nancy Pelosi for her service after she announced Thursday that she will not seek another term as the House Democratic leader. CBS News projected Wednesday that the Republicans had clinched a majority of seats in the House in the midterm elections.

Pelosi will continue to serve in the House after winning a 19th term representing Northern California's Bay Area, but will assume a lower-profile role when the next Congress convenes in January.

Reactions poured in on social media from lawmakers across the political spectrum.
