Fox Nation host Tomi Lahren slammed House Speaker Nancy Pelosi for refusing to acknowledge the crisis at the southern border.

During her weekly press briefing Thursday, Pelosi (D-Calif.) said President Trump's long-promised border wall would not prevent "tragedies" like Americans being killed by people in the U.S. illegally, and she reiterated that the wall is not up for negotiation.

On "Fox & Friends" Friday, Lahren said Pelosi should say that the the family of slain California police officer Ronil Singh, who was gunned down last month by an illegal immigrant.

"Not all crime is preventable, but crime involving illegals is 100 percent preventable," she said.

Lahren added that it's not just about crime, as undocumented immigrants put stresses on U.S. resources and infrastructure, and an unsecured border allows drugs to flow into the country.

"We have 10 to 20 million illegals in this country. Does anyone really think that doesn't burden this nation? That's my question for Nancy Pelosi," Lahren said.

She said even one life lost to an illegal immigrant is one too many, and the fact that Pelosi "casually brushes that off" shows exactly where her priorities are, and they are not with the American people or legal immigrants.
