White House Deputy Chief of Staff Stephen Miller is encouraging red states to cut public funding to educational initiatives that benefit the children of undocumented migrants, according to a report.

Miller, well known as an immigration hardliner, challenged Texas Republican lawmakers during a four-hour meeting in Washington last week about why they had not already introduced a bill to that effect, according to The New York Times.

“Do we have a RINO problem in Texas?” he asked, using an acronym MAGA conservatives employ to disparage moderates within their own camp, which stands for “Republicans in Name Only.”
