The arrests of hundreds of immigrants last week marked the first large-scale raid under the Trump administration — and the crackdown was, by all indications, just the start of much more to come.

The expansive executive order signed last month by President Donald Trump allows a significantly broader population of immigrants to be picked up for deportation. And Trump has signaled he has every intention of using that authority to carry out his campaign pledge to deport millions of foreigners from the United States.

Immigration advocates say the stepped-up enforcement amounts to a new deportation dragnet that’s ensnaring otherwise law-abiding immigrants.

“In four weeks, we’ve seen three incredibly harsh executive orders targeting the immigrant community,” said Ali Noorani, executive director of the National Immigration Forum. “This is what he campaigned on, and now the country has to deal with the consequences.”
