President Donald Trump is trying to curb illegal immigration through arrest and deportation, but some illegal immigrants who were arrested have reportedly been released back into the country.

The Department of Homeland Security, along with Immigration and Customs Enforcement, has touted daily arrest figures of immigrants since Trump was sworn in as president. However, while it has publicized some illegal immigrants being deported, some are being released into the United States under a monitoring program, according to a report from NBC News.
