A nationwide undercover operation by the Immigration and Customs Enforcement (ICE) department resulted in the arrest of 175 illegal aliens, many of whom had killed Americans.

In several jurisdictions, including the sanctuary states of California and New York, ICE agents detained roughly 200 illegal aliens who had previously been convicted of drunk driving between August 20 and September 30, according to a report by Breitbart News.

Some of the illegal aliens detained in the sting had past convictions for vehicular homicide, hit-and-run, assault, child abuse, firearms offenses, domestic violence, and fraud, in addition to drunk driving convictions.

One of these illegal immigrants was a 40-year-old Mexican man who resided in Norcross, Georgia, and was found guilty of first-degree homicide.

Another incident included a 35-year-old male illegal alien from El Salvador who was living in Bellport, New York, and was found guilty of second-degree vehicular manslaughter.

A 45-year-old male Mexican illegal alien was also detained in the operation after being found guilty of committing a fatal hit-and-run. The unlawful immigrant resided in Banning, California.

Although many criminal illegal aliens were apprehended during the sting operation, President Joe Biden's administration has drastically reduced interior immigration enforcement.

This has led to a nearly 50% drop in illegal alien arrests and a 62 percent drop in deportations of illegal alien convicts.

In May of this year, Thomas Homan, a former acting director of Immigration and Customs Enforcement (ICE), President Joe Biden is deporting just one illegal alien for every 100 that cross the border between the United States and Mexico, as Breitbart News previously reported.

While over 2.5 million illegal aliens have been discovered at the southern border since Biden entered office, according to Homan in an exclusive interview with SiriusXM Patriot's Breitbart News Daily, the ICE agency has only deported 26,000 of them.

With the fewest annual deportations in ICE's history, the statistic shows that Biden is deporting one illegal alien for every 100 illegal aliens that cross the border.

"The most historic illegal alien crossings we've ever seen in the history of this nation … in that same year, ICE had the lowest number of removals in the history of the agency," Homan said. “And it was at 59,000 [removals]. If you take away the three and a half months of Trump, they actually did 26,000 removals. Understand this, 2.5 million crossings, 26,000 removals," he continued.
