Major U.S. cities are on high alert following the President Trump’s decision to strike major Iranian nuclear facilities on Saturday, with local authorities increasing resources to protect diplomatic, religious, and cultural sites and closely monitoring any public safety threats. Federal authorities also vowed to remain vigilant following Iran’s vow to retaliate in a way that “will cause deep regret.”
While a specific credible threat is not known at this time, U.S. Customs and Border Protection Commissioner Rodney Scott issued a warning on Saturday sharing his concerns about sleeper cells in the nation.
A memo sent Saturday from CBP Commissioner Rodney Scott, obtained by The Hill’s sister network NewsNation, said “thousands of Iranian nationals have been documented entering the United States illegally and countless more were likely in the known and unknown got-a-ways.”
“Though we have not received any specific credible threats to share with you all currently, the threat of sleeper cells or sympathizers acting on their own, or at the behest of Iran has never been higher,” Scott added.
The memo urged CBP personnel to remain “vigilant.” (The Hill)
Border czar Tom Homan also warned of potential action by sleeper cells in the U.S. due to Biden’s open border.
“I pulled numbers this morning just from a CBP under Joe Biden,” he told Fox’s Maria Bartiromo. “There were 1,272 nationalists of Iran released in the country between OFO and the border patrol.”
He said his “biggest concern from Day One” has been the more than 2 million gotaways under the previous administration. “We don’t know who they are, where they came from because they got away…and that’s what’s created the biggest national security vulnerability this country has ever seen.”
