WASHINGTON (TNND) — President Donald Trump is set to mark the 100th day of his second term with an event in Michigan on Tuesday, and his administration is emphasizing progress on border security heading into the event.

The White House aims to showcase its crackdown on illegal immigration as a key achievement of Trump's presidency. The promised crackdown was a main issue for then-candidate Trump on the campaign trail.

"One of President Trump's central campaign promises was to secure the border and end this invasion. The president has overwhelmingly delivered on that promise," White House Press Secretary Karoline Leavitt said at a Monday morning press briefing.

The White House lawn now displays dozens of mugshots of immigrants with various crimes listed and the word "ARRESTED," underscoring the administration's efforts. However, the crackdown has sparked controversy, most recently after three U.S. citizen children from two families were removed from the country and sent to Honduras with their mothers.

White House Border Czar Tom Homan defended the decision.

"What we did is remove children with their mothers who requested the children depart with them. This is a parental decision, parenting 101. The mothers made that choice," Homan said.

Over the weekend, hundreds of alleged illegal immigrants were arrested in Florida and Colorado. In Colorado Springs, the DEA dismantled an underground nightclub, resulting in over 100 arrests. There were nearly 800 immigrant arrests in Florida.

Immigration remains a strong issue for Trump, although recent polls indicate Americans are divided on his handling of it as he approaches his 100th day. Democrats are hoping to capitalize on the shifting sentiments.

"There are reportedly other instances where U.S. citizen children were deported without any due process. Due process is a hallmark of what our country is all about," Sen. Chuck Schumer, D-N.Y., said.

In support of his immigration policies, Trump was set to sign two new executive orders on Monday. One empowering law enforcement and another compiling a list of sanctuary cities not cooperating with federal immigration law.
