In a Sept. 5, 2018, file photo, then Speaker of the House Rep. Paul Ryan, R-Wis., listens to President Donald Trump speak during a meeting with Republican lawmakers in the Roosevelt Room of the White House in Washington. Trump unloaded an angry late-night tweetstorm on Ryan, calling Ryan a “lame duck failure” who “had the Majority and blew it away.” Ryan is very critical of Trump in the book “American Carnage” by Tim Alberta of Politico, which had excerpts in various publications this week. Alberta wrote the former speaker could not stand the idea of another two years with the president and saw retirement as the “escape hatch.” (AP Photo/Evan Vucci, File)
