ABC News’ Rick Klein reports: Former House Speaker Newt Gingrich today flatly declared that House Speaker Nancy Pelosi should be replaced in the wake of her allegation that the CIA lied to her about harsh interrogation techniques. “She really disqualified herself to be speaker,” Gingrich, R-Ga., told Diane Sawyer on ABC’s “Good Morning America. “I think the Democrats should get a new speaker.” Pelosi’s allegation “basically smears” the U.S. intelligence community, Gingrich said, leaving her “disqualified” to be behind only the vice president in the presidential succession order. Leaving her in place, he said, is “very dangerous” for the country. Pelosi’s office called Gingrich’s suggestion “ludicrous,” and noted that no Democrats are calling for Pelosi to be ousted. The comments build on an argument Gingrich lays out in his weekly newsletter, sent to supporters Wednesday morning. “The case against Nancy Pelosi remaining Speaker of the House is as simple as it is devastating: The person who is No. 2 in line to be commander in chief can’t have contempt for the men and women who protect our nation. America can’t afford it,” Gingrich writes. “Speaker Pelosi has damaged America’s safety. . . . America is losing ground because of Nancy Pelosi’s contempt for those who defend her. Democrats owe it to their country and our national security to replace Nancy Pelosi as Speaker of the House.” For more on this topic, watch ABCNews.com’s "Top Line," live at noon ET.
