Trump says 'we've got our eyes on' Iranian sleeper cells in US

Trump said during a press gaggle Wednesday that he has been briefed on terror alerts and threats, including reported plans to conduct a drone attack in California, but he warned that any terrorists present in the country now might be the result of former President Joe Biden's "stupid open border."

"A lot of people came in through Biden with his stupid open border, but we know where most of them are: We've got our eye on all of them, I think," Trump said.

"The war itself is being prosecuted as well as anybody has ever seen, and this is other countries telling me too," he continued. "Big countries, powerful countries, they said they've never seen anything like it. And they also agree with what I'm doing. They say it's an evil country, and it's been for 47 years that way."

The warning of a California drone swarm attack is not new, having originated in February, but law enforcement has re-upped the monitoring amid Iran's threats to retaliate against Israel and the U.S.
