Roughing the tightrope: Will the head of the Pentagon leave the Trump administration? This Monday, November 9, Republican Congressman Thomas Massey launched a process to impeach Defense Secretary Pete Hegseth. Among the arguments are "starting a war with Iran without congressional approval", "deadly attacks against drug trafficking suspects" and "capturing Nicolás Maduro and Celia Flores without legal authorization". Donald Trump emphasized his support for the head of the Pentagon.
