Texas Republican U.S. Sen. John Cornyn said Thursday the FBI has granted his request to assist Texas law enforcement in locating House Democrats who fled the state, setting up a potential confrontation with Illinois Democratic officials who have vowed to protect them.

"They're grandstanding," Pritzker said, brushing off President Trump's threats. "There literally is no federal law applicable to this situation."

On the eve of the 60th anniversary of the Voting Rights Act, Texas Democrats, along with Illinois Gov. JB Pritzker and the Democratic National Chair Ken Martin, are meeting Tuesday to continue the fight against a redistricting plan to add five seats favoring Republicans.
