Mitch McConnell denounced newly elected Rep. Marjorie Taylor Greene on Monday, calling the far-right Georgia Republican’s embrace of conspiracy theories and “loony lies” a “cancer for the Republican Party.”“Somebody who’s suggested that perhaps no airplane hit the Pentagon on 9-11, that horrifying school shootings were pre-staged, and that the Clintons crashed JFK Jr.’s airplane is not living in reality,” said McConnell, R-Ky.
