Gov. Greg Abbott announced the latest transportation of illegal immigrants to so-called "sanctuary" cities on Twitter on Nov. 11.
"The 300th Texas bus of migrants just left for Chicago," the Republican governor wrote. "As [President Joe] Biden does nothing, Texas will continue taking unprecedented action to relieve our overwhelmed border communities & secure the border."
A statement from Abbott's office on Nov. 4 said that Texas has bused almost 8,300 illegal immigrants to Washington, D.C. since April, over 3,500 to New York City since Aug. 5, and more than 1,100 to Chicago since Aug. 31 as part of its effort to secure the border.
The governor's office says the busing mission is "providing much-needed relief to our overwhelmed border communities."
Abbott and other Republicans have criticized Biden's open border policies for creating a crisis that has seen record-breaking numbers of illegal immigrants attempting to enter the United States.
Record Number of Arrests at Border
Roughly 4.9 million people have illegally crossed into the United States from Mexico since Biden took office in January 2021, according to a report released in August.
