The 300th bus filled with migrants left Texas on Thursday for Chicago as President Biden continues to ignore the border, Texas Gov. Greg Abbott said. 

The latest bus operation is part of an effort by Abbott to transport illegal immigrants released into border towns to liberal areas with sanctuary city policies in an effort to bring attention to the crisis unfolding at the U.S.-Mexico border.

“The 300th Texas bus of migrants just left for Chicago,” Abbott tweeted. “As Biden does nothing, Texas will continue taking unprecedented action to relieve our overwhelmed border communities & secure the border.”

Abbott and other Republicans have criticized the Biden administration for not doing enough to secure the border as record-breaking numbers of migrants continue to overwhelm border agents and the cities in which they are released. 

He has touted Operation Lone Star, a joint mission to combat illegal immigration and crime at the border, since the effort launched in March. 

In October, he said more than 336 million lethal doses of fentanyl have been seized since it began. In October, more than 64,000 illegal immigrants evaded the Border Patrol while another 205, 000 were apprehended.
