If so this was an individual claim, it’s not known to be official policy, the law doesn’t support it, and it hasn’t been used as a successful argument in court. This claim comes up regularly but it’s a misinterpretation/rumor. People should stop repeating it or it will become one of those “folk truths” that eventually becomes accepted and real.

It's not a folk truth that I saw it, in a mainstream news report, said by a Border Patrol employee to justify their actions more than 100 miles from the border. That's not a misinterpretation; that really happened. At least once.

I would be delighted for it to not have been an actual administration claim, ever.
