President Donald Trump on Wednesday signed an executive order that directs federal agencies to start building a U.S.-Mexico border wall and institute a crackdown on immigration, in the first of a series of measures expected this week.

Trump signed the actions during a visit to the Department of Homeland Security, where he said, “A nation without borders is not a nation. Beginning today, the United States of America gets back control of its borders.”

The order for the wall instructs agencies to erect “a large physical barrier on the southern border.”

Others seek to slash immigration and stiffen penalties for undocumented people.

The Hill reports:

“We’re going to strip federal grant money from the sanctuary states and cities that harbor illegal immigrants,” Spicer said.

Marielena Hincapie, executive director of the National Immigration Law Center, called the border wall plan “incoherent and a monumental waste of taxpayer money.”

United Farm Workers president Arturo S. Rodriguez noted that “U.S. Department of Labor surveys show the majority of U.S. farm workers are undocumented…So if today’s executive orders from Donald Trump signal the beginning of fulfilling his oft-repeated campaign pledge to deport the undocumented, then who is going to feed America?”

“Who is going to feed the guests at Trump hotels and golf courses?” Rodriguez said. “Who is going to feed Donald Trump?”

Stephanie Taylor, co-founder of the Progressive Change Campaign Committee, said the new policies were “fueled by hate and contradict what America is all about.”

César J. Blanco, political director of the Latino Victory Project, said, “The executive actions on immigration announced by President Trump today are simply un-American. President Trump’s executive actions go against the principles and values that our country was founded on and will only tear families apart. These executive actions seem to be part of his efforts to delegitimize our democracy and our values. We must respond to his actions by defending Latinos and all minorities from threats against our humanity.”

The actions also include a crackdown on sanctuary cities. Erik Andiola, political director of Our Revolution, said Trump’s targeting of these cities presents “an ultimatum: either states comply with federal immigration enforcement officials who want to tear families apart, or they risk losing critical funding for much-needed services. This is a direct attack on progressive states and the policies they support. This moment requires that we come together to protect those who are most vulnerable under Trump’s administration.”
