Biden: Trump's 'Toxic Tongue' Linked to Mass Shootings

Joe Biden is accusing President Donald Trump of fueling the white supremacy that's blamed for several mass shootings in the United States in a speech the Democrat was due to deliver Wednesday.

Biden, 76, frontrunner in the crowded pack of Democras running for the White House, was scheduled to speak in Iowa after back-to-back mass shootings last weekend in the United States.

In the first, on Saturday, a gunman killed 22 people in El Paso, a Texas city on the border with Mexico. Law enforcement agencies say he apparently was driven by hatred for Hispanics.

In the second mass shooting, a gunman in Dayton, Ohio, killed nine people, including his sister, before he was killed by police.

Trump's rhetoric, including calling Central Americans trying to enter the United States "an invasion," and his hard-line immigration policies have exposed him to condemnation since the El Paso shooting.

"How far is it from Trump's saying this 'is an invasion' to the shooter in El Paso declaring 'his attack is a response to the Hispanic invasion of Texas?' Not far at all," Biden was due to say, according to an advance copy of his speech.

"In both clear language and in code, this president has fanned the flames of white supremacy in this nation."

Trump aides deny his rhetoric was a cause of the shootings. In a national address, the president proposed reforming mental health laws, working with social media to detect possible mass shooters and keeping guns away from people considered potentially violent. He plans to visit El Paso on Wednesday.
