Pelosi is the first and only woman ever to serve as speaker of the House. While she was recently elected to another term in office, she has opted not to seek the leadership role again. She has served as a lawmaker in the U.S. House of Representatives for more than three decades.
"John Boehner crying as he paid tribute to Nancy Pelosi is the perfect symbol of uniparty pathology," Monica Crowley tweeted.
"Boehner crying in tribute to Pelosi while talking about how his daughters are Democrats is a pretty good summation of Republican leadership over the past couple of decades," Ben Shapiro tweeted.
"While you’re sniveling at Pelosi’s portrait reveal, conservatives are weeping for America — precisely because our country’s greatness and potential have been squandered by The Uniparty..." Tim Meads wrote.
Guy Benson tweeted, "In fairness, Boehner cries about everything."
