"Redline" protest in front of Dallas City Hall in downtown Dallas, Texas.Th term red line was used to mobilize protestors after the President acts to impede, curtail, or in any way interfere with the Mueller Investigation. The protest is part of a nationwide campaign against President Trump’s firing of Attorney General Jeff Sessions and naming Matthew Whitaker, a Trump loyalist to fill the position and removing Deputy Attorney general Rod Rosenstein oversight over the Mueller probe into the White House. The move is seen as a threat to the integrity of Special Counsel Robert Mueller’s investigation of the administration.
