>> Cracking down on sanctuary cities.>> President Trump laying siege to local governments that shield illegal immigrants. But it's unclear whether he actually has the ability to back up his tough talk.>> I'm Andy Sullivan in Washington where Trump has signed an executive order that would cut off federal funds to cities like Chicago and Los Angeles that ignore requests to hand over illegal immigrants.
It's yet another example of Trump acting quickly to fulfill his campaign promises, maybe too quickly. Legal experts telling us that the executive orders is filled with sweeping language but displays little knowledge of how the federal government actually hands out money. Over the past few years, the Homeland Security Department has focused on deporting illegal immigrants who are already in jail.
The idea being that they should first remove known troublemakers before they go after those who aren't breaking any laws. But dozens of cities and counties across the United States have refused to cooperate, saying that would make immigrants less willing to help local police solve crime. That's angered Trump, who campaigned with parents whose children have been murdered by illegal immigrants.
His executive order, signed Wednesday, says cities that don't follow immigration law can't get federal aid. That's a huge pot of money. Uncle Sam handed out $652 billion in the most recent fiscal year, almost all of that going to state and local governments for things like healthcare, school lunches, highway construction.
But here's the catch, experts telling us that there are all sorts of restrictions on how that money can be used. If a city is defying immigration orders, for example, the feds can cut off law enforcement dollars but can't interfere with pre-school money or HIV prevention funds, for example.
And even here, he may have shot himself in the foot because his order says he has to keep those law enforcement dollars flowing. So when cities and immigrant groups inevitably challenge this order in court, they may find that there is not actually any bite behind Trump's bark.>> They're gonna be gone fast.
