In an interview with Face The Nation's Margaret Brennan to be broadcast on Sunday, President Donald Trump accused House Speaker Nancy Pelosi (D-CA) of being responsible for the deaths of American citizens.

Speaking with host Brennan about his desire to receive billions in funding for his border wall, Trump lashed out at the House Speaker who has foiled him so far.

According to Trump, Pelosi is doing a "terrible disservice to our country."

"She's — she's costing the country hundreds of billions of dollars because what's happening is, when you have a porous border and when you have drugs pouring in, and when you have people dying all over the country because of people like Nancy Pelosi who don't want to give proper border security for political reasons — she's doing a terrible disservice to our country," Trump said.
