Commenting on President Donald Trump's address to the nation about border security and the response of Sen. Chuck Schumer (D-N.Y.) and House Speaker Nancy Pelosi (D-Calif.), conservative talk radio host and best selling author Mark Levin said the two Democrats are "pathological liars" who have been in Congress half-a-century and yet have done "nothing" about the border.

Levin, who worked in the Reagan Justice Department, added that neither Pelosi nor Schumer talked about the low-skilled American worker who is harmed by illegal alien labor -- aided and abetted by multi-national corporations -- and didn't talk about the "communities on the border that are suffering."

He further explained that the 2008 Democrat Party platform on border security and illegal immigration "basically supports virtually everything the Republican president of the United States said today," but now, for power reasons, the Democrats "want to drag us all off the cliff with them."

“Well, first of all, the president gave an outstanding speech, was concise," said Levin on Fox's Hannity on Tuesday night. "It was compassionate and truly compassionate. He provided the context and both in terms of what's going on at the border, the expense which is de minimis and who is really responsible.

Levin continued, "Now, let's keep a few things in mind when you watch Schumer and Pelosi. They are pathological liars. They've been in Congress over half a century. What the Hell have they done about the border? Nothing."

"They're part of the scam artists," he said. "They get amnesty, legalization, citizenship, and never secure the border. Just spend billions and trillions more, more debt, more deficits on the redistribution of wealth, on $200-billion-a-year on illegal aliens."

"One more time: They fooled Reagan, they fooled Bush 41, they fooled Bush 43, but they're not going to fool Donald Trump who's dealt with tougher than Pelosi and Schumer," said Levin.

"These two and the rest of them are never forced to explain their flip-flop," said the best selling author. "Where they were for border security, they voted to authorize walls, they voted to fund some of the walls, and now all of a sudden it's immoral."

"You know what's immoral?" he said. "When everybody talks about those government employees will be temporarily inconvenienced, who will get their money back. But nobody talks about the unskilled, low-skilled American worker who has to compete with people from Guatemala, from Honduras, from Mexico from south of the border who come into this country illegally."

"Nobody talks about the big corporations like Hewlett-Packard and Boeing and Disney and others, who are part of the scam artist operation, who want illegal aliens in this country," said Levin.

"Nobody talks about the fact that destroying our immigration system these Democrat cities, sanctuary cities, these Democrat states, sanctuary states, where the citizens are treated as second-class citizens, and the taxpayers have to cough up the money -- for what?"

Levin continued, "Let me explain what this is about: Power. Democrat Party power. Democrat Party before country. There's an excellent piece, in of all places, The Atlantic, a left-wing site, written by a guy by the name of Peter Beinart, a liberal. And he says, between 2008 and ‘16, the Democrats became more and more confident that the country's growing Latino population gave the party electoral edge."

"So they switched," he said. "They declared after Obama's 2008 win, if that pattern continues with the Latino vote, the GOP is doomed for 40 years of wandering in the desert. And he goes on to explain this -- this is a liberal and a liberal site. That is exactly what's going on."

"Notice Pelosi and Schumer didn't talk about the American worker," said Levin, who also hosts Life, Liberty & Levin on the Fox News Channel. "Notice they didn't talk about the communities on the border that are suffering. Notice they never talk about law and order, because they hate law enforcement. They never talk about the overwhelming costs involved in health care, the overwhelming costs involved in our public schools. Localities and states they're barely reimbursed for this."

Concluding his comments, Levin said, "The Democrat platform in 2008 basically supports virtually everything the Republican President of the United States said today. The American people haven't changed. The Republican Party hasn't changed. The Democrats for political reasons and power reasons, they've changed and they want to drag us all off the cliff with them."
