Leading Illinois Democrats and the head of the national Democratic party joined Texas House Democrats this week in a call for a political redistricting fight to expand to a national battle on Tuesday.

Michael McAuliffe, former prosecutor and former state attorney, told Newsweek the FBI's involvement is "well beyond alarming."

The FBI will help Texas track down Democratic state lawmakers who left the state as part of a collective effort to thwart state Republican efforts to redraw congressional districts, Republican U.S. Senator John Cornyn said on Thursday.
