Gov. J.B. Pritzker on Friday sent Texas Gov. Greg Abbott a sweeping letter about the ongoing migrant crisis, urging him to stop dropoffs during a dangerous winter storm.“While action is pending at the federal level, I plead with you for mercy for the thousands of people who are powerless to speak for themselves,” Pritzker said in the letter. “Please, while winter is threatening vulnerable people’s lives, suspend your transports and do not send more people to our state.”
