Trump would extend 'Dreamers,' TPS protection in exchange for full border wall funding; Democratic leaders reject plan as 'non-starter'

President Donald Trump announced on Saturday that in exchange for border wall funding and ending the partial government shutdown, he would extend temporary protections for so-called "Dreamers" and those with Temporary Protected Status -- two key issues for congressional Democrats who nevertheless held their ground on refusing the president's demand for $5.7 billion in wall funding.

"Our plan includes the following," Trump announced in a speech from the Diplomatic Reception Room. "$800 million in urgent humanitarian aid, $805 million for drug detection technology to help secure our ports of entry, an additional 2,750 border agents and law enforcement professionals [and] 75 new immigration judge teams to reduce the court backlog..."

Additionally, Trump promised "critical measures to protect migrant children from exploitation and abuse," and "a new system to allow Central American migrants to apply for asylum in their countries."

In return, Trump said he wants his $5.7 billion in border funding, which he said would be "a strategic deployment of physical barriers, or a wall."

Trump added that he and Republicans “hope [Democrats] will offer their enthusiastic support and I think many will. This is a common sense compromise both parties should embrace. The radical left can never control our borders. I will never let it happen.”

Trump also said that Senate Majority Leader Mitch McConnell would bring the proposal to a vote in the Senate this week.

Trump noted that he promised a wall on the southern border during his campaign and “I intend to keep that promise one way or another."

"Our immigration system should be the subject of pride, not as a source of shame....our immigration systems should be the envy of the world, not a symbol of disunity and dysfunction. These problems can all be solved.”

Yet, before Trump even made his 4 p.m. speech, House Democrats were calling it a "non-starter."

Twenty-five minutes before the planned start of the president's speech, House Speaker Nancy Pelosi released a statement, saying that "initial reports" about Trump's announcement "make clear that his proposal is a compilation of several previously rejected initiatives, each of which is unacceptable and in total, do not represent a good faith effort to restore certainty to people’s lives."

"It is unlikely that any one of these provisions alone would pass the House, and taken together, they are a non-starter," Pelosi continued in the statement. "For one thing, this proposal does not include the permanent solution for the Dreamers and TPS recipients that our country needs and supports," Pelosi said, referring to Temporary Protected Status designations.

Pelosi also said that House Democrats would pass a package of "six bills agreed to by House and Senate negotiators and other legislation to re-open government so that we can fully negotiate on border security proposals."

After the speech, Senate Minority Leader Chuck Schumer rejected Trump's plan.

“It’s clear the President realizes that by closing the government and hurting so many American workers and their families, he has put himself and the country in an untenable position," Schumer said in the statement. "Unfortunately, he keeps putting forward one-sided and ineffective remedies. There’s only way out: open up the government, Mr. President, and then Democrats and Republicans can have a civil discussion and come up with bipartisan solutions."

“It was the President who single-handedly took away DACA and TPS protections in the first place –- offering some protections back in exchange for the wall is not a compromise but more hostage-taking.”

Early Sunday, the president criticized Pelosi and other Democrats for not seeing "crime & drugs"

"They only see 2020 - which they are not going to win. Best economy!" he said in a tweet. "They should do the right thing for the Country & allow people to go back to work."

Reaction from immigration advocates was swift and resistant.

“Trump must reopen the government now and Congress must not let Trump use the suffering he caused for immigrant youth and federal workers to force his mass deportation agenda on the country,” said Greisa Martinez Rosas, deputy executive director of United We Dream -- the nation’s largest immigrant youth-led advocacy group, in a statement posted to the organization’s verified Twitter account.

“The ‘deal’ he announced today would mean more kids in cages, more deportations and more misery,” Martinez Rosas continued in her statement. “The American people support citizenship for undocumented people and disagree with mass deportation and his wall. Congress should pass clean, permanent protections for undocumented immigrants, defund the deportation force and not play along with Donald Trump’s sick and dangerous game.”

A spokesperson for an immigrant organization named Make the Road, which has chapters in five U.S. states, called on Congress to "reject any border wall deal from Trump, and to re-open the government right away."

"Trump is the one who ended Deferred Action for Childhood Arrivals (DACA) and Temporary Protected Status (TPS) programs, jeopardizing millions of immigrants and their families. He has no right to use us as a pawn in his political games.”

Bi-partisan legislation known as the BRIDGE Act (Bar Removal of Individuals who Dream and Grow our Economy) would extend protections and provide work authorization for three years for TPS individuals and "Dreamers" -- some 750,000 young, undocumented immigrants who arrived in the U.S. as children and have met the requirements to participate in the Deferred Action for Childhood Arrivals (DACA) program.

The continuing shutdown -- which could head into its second month this week -- affects about a quarter of the federal government. Trump has said he will keep the government shut down until and unless the Democrat-controlled House of Representatives heed his demand for $5.7 billion to build more than 200 miles of walls between the U.S. and Mexico borders. Democrats recently offered about $1.3 million for border barrier funding.

Trump’s announcement followed a visit Saturday morning to Dover Air Force Base in Maryland, where the president met with the families of the four Americans killed in Manbij, Syria. At the base, Trump participated in the dignified transfer of Scott Wirtz, a 42-year-old civilian contractor who was killed in the deadly ISIS bomb blast on Wednesday.

The so-called transfer of the remains of a fallen military member unfolds with strict solemnity, as a casket draped in an American flag is carried off an aircraft to a waiting vehicle which takes the remains to a mortuary.

In a somber moment, the president walked on board a C-17 aircraft that held the transfer case. Inside, a chaplain led a prayer over the deceased. The president, who was joined by Secretary of State Mike Pompeo and acting Secretary of Defense Patrick Shanahan, stepped off the plane and stood silently in formation with his right hand in a salute as the case was carried to a transfer vehicle by the Navy Ceremonial Team.

The four Americans -- an interpreter, a Navy chief cryptologic technician, a Department of Defense civilian and an Army chief warrant officer -- were killed in a suicide bombing last week, the deadliest attack on US military since troops went into Syria. ISIS claimed responsibility for the attack.

The deadly bomb blast came one month after President Trump declared plans to withdraw U.S. troops from Syria, having – he said -- completed the mission to defeat ISIS.

This is not the president's first time to pay his respects to the fallen at Dover. Last February, the president made an unannounced trip with Ivanka Trump for the dignified transfer of a Navy SEAL killed in Yemen.

Before departing for Dover the president told reporters on the White House South Lawn that meeting with the family members of fallen soldiers is one of the "toughest things I have to do as president."

"I think it is the toughest thing I have to do," Trump said. "When I'm going to meet relatives of some of our great, great heroes that have fallen, I think it might be the toughest thing I have to do as president."

In a video posted to Twitter Friday evening, Trump called the situation at the southern border both a "humanitarian crisis" and a "national security crisis." He added that it would be necessary to secure the border and that "if we don't do that, we're a very, very sad and foolish lot."

The president's promised announcement came amid an increasingly nasty back-and-forth with Democratic leaders over the protracted government shutdown -- which this week could head into its second month -- and funding over his long-desired border wall.

After House Speaker Nancy Pelosi asked the president to postpone his State of the Union speech due to security shortages brought on by the shutdown, Trump blocked her use of a military aircraft for an official overseas trip with a congressional delegation, and suggested that she could make the trip to the war theater in Afghanistan.

On Friday, Pelosi accused the president and his administration of leaking her plans to possibly fly commercially instead and endangering lives as a result.

Immediate reaction among Trump's base was mixed, with conservative commentators Laura Ingraham and Ann Coulter offering opposing takes on the speech.
