WASHINGTON _ During his presidential campaign, no single promise electrified Donald Trump's supporters more than the pledge to build a "big, beautiful wall" all along the border with Mexico.
Wednesday, President Trump turned that promise into an executive order, one of two he signed. His directive leaves many questions unanswered about what sort of wall might be built, how much it would cost and how it would be paid for.
The two orders, however, do begin the crackdown on illegal immigration that Trump promised. In addition to the wall, he would greatly expand deportations and detention of migrants and block federal money for so-called sanctuary cities.
Some of the actions will be felt immediately, some require more cash from Congress, and others will only take effect over time.
Here's a look at what the actions mean and what they don't.
