A group of House Republicans barged into the secure room where the Pentagon's top official on Ukraine was testifying in the impeachment inquiry — holding up proceedings for hours, demanding access to the closed-door sessions where only members of the three committees overseeing the inquiry have been allowed. But while Republicans attack the process, Democrats are fighting to keep focus on the content of the inquiry, including revealing new testimony from acting U.S. ambassador to Ukraine William Taylor. Jim Braude was joined by James Rappaport, Trump supporter and former chair of the Massachusetts Republican committee; and Gautam Mukunda, a Harvard Kennedy School fellow and author of "Indispensable: When Leaders Really Matter."
