President Trump implored congressional Democrats to help pass a spending bill that would fund a border wall, in his address to the nation Tuesday night.

Trump described the situation at the southern border as a "humanitarian and security crisis," and that "uncontrolled" illegal migration is hurting American citizens.

"Over the years, thousands of Americans have been brutally killed by those who have illegally entered our country," Trump said. "And thousands more lives will be lost if we don't act right now."

Law enforcement professionals have requested $5.7 billion to fund a physical barrier, he said, which -- at the request of Democrats -- would be made of steel.

"This is just common sense. The border wall would very quickly pay for itself," Trump said, adding that such a wall would be paid for indirectly by the the United States-Mexico-Canada Agreement.

The president also said the partial government shutdown has not ended due to Democrats refusing to fund border security.

"This situation could be solved in a 45-minute meeting," he said, calling on members of Congress to pass a bill that would end the border "crisis."

"This is a choice between right and wrong. Justice and injustice. This is about whether we fulfill our sacred duty to the American citizens we serve."

Following Trump's address, Senate Democratic Leader Charles Schumer of New York and House Speaker Nancy Pelosi of California gave an opposition response.

Pelosi called on Trump to "end the shutdown and meet the needs of the American people."

She said his speech was "full of misinformation and malice" and that Trump has "chosen fear [over] facts."

"Women and children at the border are not a security threat," she said.

Schumer added that the president is upset that he "failed" in making Mexico pay for the wall, then failed to convince Congress to fund the wall.

"We don't govern by temper tantrum," he said.

"[Trump] used the backdrop of the Oval Office to manufacture a crisis," the Brooklynite added.
