Texas taxpayers have shelled out a whopping $10 billion for their state’s border security effort, Texas Gov. Greg Abbott says — and the state can’t afford four more years of chaos at the border.

Abbott told The Post in an exclusive interview that he believes Vice President Kamala Harris will not work with him to secure the border if she is elected.

His evidence, he said Harris has been invited multiple times to tour the Texas border, and “She never has ever even responded.”

“She’s refused to step up” — despite Biden giving her responsibility for stopping the flow of illegal migrants, he said.
