President Donald Trump moved aggressively to tighten the nation's immigration controls Wednesday, signing executive actions to jumpstart construction of a U.S.-Mexico border wall and block federal grants from immigrant-protecting "sanctuary cities."
"Beginning today the United States of America gets back control of its borders," Trump declared during a visit to the Department of Homeland Security. "We are going to save lives on both sides of the border."
Trump cast his actions as fulfillment of a campaign pledge to enact hard-line immigration measures, including construction of a wall paid for by Mexico. With the families of Americans killed by people living in the U.S. illegally sitting in the audience, Trump said, "When it comes to public safety, there is no place for politics."
Funding for the border wall project is murky. While Trump has repeatedly promised that Mexico will pay for it, U.S. taxpayers are expected to foot the bill and the new administration has said nothing about how it will compel Mexico to reimburse the money. One of the executive actions Trump signed Wednesday appears to signal that he could restrict aid to Mexico.
Mexican President Enrique Pena Nieto, who reiterated Wednesday evening that Mexico will not pay for it, is expected to meet with Trump at the White House next week, despite calls from some lawmakers for him to cancel his visit.
Congressional aides say there is about $100 million of unspent appropriations in the Department of Homeland Security account for border security, fencing and infrastructure. That would allow planning efforts to get started, but far more money would have to be appropriated for when construction got underway.
In an interview with MSNBC's Greta Van Susteren Wednesday, House Speaker Paul Ryan said there are many different ways to get Mexico to contribute to paying for the wall and "there are different ways of defining how, exactly they pay for it." Ryan also confirmed that price tag estimates of $8 billion to $14 billion are "about right."
Trump has insisted many times the border structure will be a wall. The order he signed referred to "a contiguous, physical wall or other similarly secure, contiguous and impassable physical barrier."
Citing a "crisis" at the southern border, the president's orders also call for hiring 5,000 additional border patrol agents, though the increase is subject to congressional approval. He also moved to end what Republicans have labeled a catch-and-release system at the border. Currently, some immigrants caught crossing the border illegally are released and given notices to report back to immigration officials at a later date.
But Trump's attempt to fix America's broken immigration system with a border wall appears to be misguided. According to the Pew Research Center, net migration flows from Mexico have been negative since 2008. In other words, more Mexicans are leaving the country than entering. In 2014, there were 5.8 million Mexican undocumented immigrants living in the U.S., down from 6.4 million in 2009 and lower that the peak in 2007 of 6.9 million.
Meanwhile, the number of undocumented immigrants from countries other than Mexico grew by 325,000 since 2009, to an estimated 5.3 million in 2014, according to Pew. Populations went up most for origin countries in Asia and Central America, but the number also ticked up for those from sub-Saharan Africa.
Later in the week, Trump is expected to sign orders restricting the flow of refugees into the United States. His current proposal includes at least a four-month halt on all refugee admissions, as well as a temporary ban on people coming from some Muslim-majority countries, according to a source from a public policy organization that monitors refugee issues. The person was briefed on the details of that proposed action by a government official and outlined the plan to The Associated Press.
The public policy organization source insisted on anonymity in order to outline the plans ahead of the president's official announcements.
Trump campaigned on pledges to tighten U.S. immigration policies, including strengthening border security and stemming the flow of refugees. His call for a border wall was among his most popular proposals with supporters, who often broke out in chants of "build that wall" during rallies.
In response to terrorism concerns, Trump controversially called for halting entry to the U.S. from Muslim countries. He later turned to a focus on "extreme vetting" for those coming from countries with terrorism ties.
To build the wall, the president is relying on a 2006 law that authorized several hundred miles of fencing along the 2,000-mile frontier. That bill led to the construction of about 700 miles of various kinds of fencing designed to block both vehicles and pedestrians.
The Secure Fence Act was signed by then-President George W. Bush, and the majority of that fencing in Texas, New Mexico, Arizona and California was built before he left office. The last remnants were completed after President Barack Obama took office in 2009.
The Trump administration also must adhere to a decades-old border treaty with Mexico that limits where and how structures can be built. The 1970 treaty requires that structures cannot disrupt the flow of the rivers, which define the U.S.-Mexico border along Texas and 24 miles in Arizona, according to The International Boundary and Water Commission, a joint U.S.-Mexican agency that administers the treaty.
Trump's order to crack down on sanctuary cities — locales that don't cooperate with immigration authorities — could cost individual jurisdictions millions of dollars. But the administration may face legal challenges, given that some federal courts have found that local jurisdictions cannot hold immigrants beyond their jail term or deny them bond based only a request from immigration authorities.
It appeared as though the refugee restrictions were still being finalized. The person briefed on the proposals said they included a ban on entry to the U.S. for at least 30 days from countries including Iran, Iraq, Libya, Somalia, Sudan and Yemen, though the person cautioned the details could still change.
There is also likely to be an exception for those fleeing religious persecution if their religion is a minority in their country. That exception could cover Christians fleeing Muslim-majority nations.
As president, Trump can use an executive order to halt refugee processing. Bush used that same power in the immediate aftermath of the Sept. 11 attacks. Refugee security vetting was reviewed and the process was restarted several months later.
