“Many Salvadorans, Haitians & Nicaraguans have lived, worked and paid taxes in the US for decades. This is their home. We must #SaveTPS,” Warren added, referencing provisions in a bill she is backing.

On Monday Nielsen said deportations will be delayed so El Salvador can “prepare for the return and reintegration of its citizens” and so hundreds of thousands of people under threat of being deported can “arrange for their departure or to seek an alternative lawful immigration status in the United States.”

Nielsen said the conditions caused by the earthquake “no longer exist” after reconstruction efforts and that Congress could create legislation that would offer the Salvadoran immigrants legal status. The delay, she said, would allow politicians to do just that.

Under the Safe Environment From Countries Under Repression and in Emergency Act (SECURE Act), sponsored by Warren and several other Senate Democrats last November, those with protected TPS status and their families would be able to gain permanent resident status and a path to citizenship.

The Democrats’ SECURE Act shouldn’t be confused with another, introduced by Republican Chuck Grassley near the end of last year, called the Security, Enforcement, and Compassion United in Reform Efforts Act, also known as the SECURE Act, which offers an immigration enforcement crackdown.

“We stand with you and we will do all we can in Congress to #SaveTPS,” said Representative Pramila Jayapal in a statement Monday about the planned mass deportation. She pointed out that immigrants who have been members of American society for years would be forced back to a nation that in 2016 was “named the world's most violent country.”

The deportations would contribute to a combined $31 billion hit to the American economy if TPS holders are removed from the U.S. en masse, wrote Representative Zoe Lofgren (D-Calif.), who is the ranking member on the Immigration and Border Security Subcommittee in the House, in a statement.

“This will not just affect Salvadorans, but also their U.S. citizen spouses and children, the American employers and employees who depend on them,” Lofgren tweeted.

Around 437,000 immigrants from countries like El Salvador, Nicaragua, Haiti and Honduras who are under TPS protection for various reasons—including violence and environmental disasters—are in limbo after the Trump administration has moved to remove them in recent months, pointed out the human rights group Oxfam in a post Monday.

“It doesn't make America safer. It doesn't make America stronger,” Warren saidMonday, calling the Trump administration’s moves for mass deportations “fundamentally wrong.”

“It takes away people who work hard,” she said, “and it takes away the message to the world that we are a beacon of liberty and that we stand for those who need a place of safety.”
