President Donald Trump’s “largest-ever” mass deportation has led to the arrests of thousands of illegal immigrants in the first 10 days of his presidency, but the new administration has a ways to go if it intends to surpass the Obama administration’s massive first-term figures.

The operation started on Day One, Jan. 20, with arrests of illegal immigrants across the nation, and it has quickly ramped up since then. It topped 2,300 arrests in the first week, reaching approximately 5,500 in 10 days.
