Conservative commentator Ann Coulter said that the U.S. should close its borders for 10 years and blamed "left-wingers who hate America" for corrupting the U.S. immigration system.

During an interview with PJ Media to promote her new anti-immigration book, titled "¡Adios, America!," Coulter criticized the federal government for failing to enforce laws that would prevent criminals from migrating to the U.S.

"There's a law on the books that says if a country will not take a criminal back the attorney general shall, not may, shall deny visas, any visas coming from that country -- that is on the books right now. Has it been enforced by Republicans or Democrats? No, it has not," said the political pundit.

The author went on to mention another U.S. law which she said government officials have failed to enforce.

"There's a law on the books right now that says an immigrant who has been convicted of a crime in America who does not cooperate in being sent home, that itself is a crime, not signing the papers, not showing up when you're supposed to, that itself is a crime punishable by four years in prison -- that's never enforced. It's just not enforced," said Coulter, adding, "Three times Congress has voted to build a fence, and it never gets built."

At another point during the interview, the controversial critic suggested that the U.S. implement a 10-year freeze on immigration because the system cannot be rehabilitated with a legal fix.

"The entire thing has to be shut down. No more immigration for 10 years. We get our books in order. We assimilate the ones already here. Build a fence. Repeal anchor babies and then we start up with the pre-1970 immigration policies," Coulter said.

Coulter continued, "The entire immigration bureaucracy is corrupt. It is run by and staffed by left-wingers who hate America who in other times would have been fighting with revolutionaries in Latin America and getting themselves arrested. Now they punish Americans here at home. They say we are racist, sexist, imperialistic, greedy, they want to transform America because they hate America," she added.

According to Coulter, the demographic that has suffered the most from immigration are African-Americans.

"Particularly, it's African-Americans who are hurt the most by all of this low-wage immigration. It's driving their wages down. It's killing them in the job market," she said.
