BOSTON (CBS) – President Donald Trump signed executive orders Wednesday that jump-start construction of a US-Mexico border wall and strip funding for sanctuary cities.

Mayor Marty Walsh denounced the president’s plan and is promising immigrants they will have a safe space in Boston.

“The latest executive orders and statements by the president about immigrants are a direct attack on Boston’s people, Boston’s strength and Boston’s values,” Walsh said.

The mayor said 28 percent of Boston residents are immigrants and 48 percent have at least one foreign born parent.

“I want to say directly to anyone who feels threatened today or vulnerable you are safe in Boston,” Walsh said. “We will do everything in our power to protect you – if necessary we will use City Hall itself to shelter and protect anyone who is targeted unjustly.”

The mayor said that people could also sleep in his office if they need to.

Undocumented immigrants like Estrella Lopez from Mexico are also reacting to the President’s executive orders.

“If you are a father, you have daughters, you have sons, you have to be very cautious what you are doing to the families that are living here in the United States,” Lopez said.
