Democrats in New York, California and Illinois are threatening to redraw their own maps in retaliation to Republican redistricting efforts in Texas.

Illinois Gov. JB Pritzker called the Texas Democrats "heroes" at a joint press conference this morning in the Chicago area. Why it matters: President Trump's push to redraw Texas' congressional map is designed to net the GOP up to five House seats — potentially enough to decide the majority for Trump's final two years in office.

A bomb threat was made against Texas Democratic lawmakers who are in Illinois, the Illinois governor and Texas lawmakers said Wednesday morning.

A delegation of Texas House Democrats had to evacuate their hotel in Illinois Wednesday morning due to a potential bomb threat, according to multiple lawmakers and local police.
