After President Trump's campaign-style speech in Arizona this week, Democrats are still balking at his call to build a border wall.

Like it or not, the numbers are firmly on Trump's side.

Illegal border crossings under Trump's administration are down 53 percent to 76 percent depending upon who you listen to, which shows that cracking down on illegal immigration works.

However, the illegal immigration crisis still looms large.

According to the United Nations, no conservative think tank, 97 percent of illegal immigrants who enter this country clandestinely do so via the southern border.

The Democrats have long pushed the theory that they're coming strictly for jobs.

But the House Committee on Homeland Security has debunked that theory saying, "Not all illegal aliens are crossing into the United States to find work," a report by the Homeland Security Committee reveals. "Law enforcement officials indicate that there are individuals coming across the border who are forced to leave their home countries because of criminal activities. These dangerous criminals are fleeing the law in other countries and seeking refuge in the United States."

There are no two ways about it: Many illegal immigrants are coming here to commit crimes.

According to FBI crime statistics, a stunning 95 percent of arrest warrants issued in Los Angeles are for illegal immigrants, not American citizens.

A shocking 75 percent of criminals on law enforcement's "Most Wanted" listd in Los Angeles, Phoenix, and Albuquerque, N.M., are also illegal immigrants.

In addition, 53 percent of all investigated burglaries reported in California, New Mexico, Nevada, Arizona, and Texas have been perpetrated by illegal aliens.

As a result, illegal immigrant criminals are also clogging up our correctional facilities and costing taxpayers big time.

Immigrants, legal or illegal, make up 20 percent of inmates in prisons and jails nationally, according to a 2009 study by the Center for Immigration Studies. Immigrants make up about 7 percent of the U.S. population, census data show. The annual cost to house these criminal illegal immigrants nationally is $1.6 billion and growing by the year.

FBI crime statistics show that number is even higher for the largest border state, California. About 25 percent of inmates inside California's state prisons, county jails, and municipal detention facilities are Mexican nationals.

Then, there is the total cost of taking illegal immigrants into newly-forged sanctuary cities.

When Trump issued his recent executive order cracking down on sanctuary cities and threatening to withhold federal funding from those cities, it was revealed that the annual taxpayer burden adds up to more than $14 billion nationally, $1 billion in California and Texas, and more than $100 million annually in at least a dozen states.

However, Democrats don't appear to be interested in the cost of illegal immigration, and they certainly seem hell-bent on obstructionism in order to divebomb this president's agenda.

Contrast this to 10 years ago when Democratic senators by the name of Hillary Clinton, Barack Obama, and Joe Biden joined 77 other senators to vote in support of a border barrier in Yuma, Ariz., which succeeded in reducing illegal immigrant crossing by a whopping 70 percent.

Democrats can't help themselves. Just like former Sen. John Kerry, they were for a policy before they were against it!

When it comes to immigration, always remember: Politicians may change sides over the years, but the numbers never do.

In fact as the statistics demonstrate, the numbers continue to increase each year that Democrats don't act.
