Twelve suspicious packages were sent to prominent Democratic leaders and celebrities, including two today to former DNI director James Clapper and Sen. Cory Booker (D-NJ). The other 10 were addressed to former President Obama, Hillary Clinton, former Vice President Joe Biden, former CIA director John Brennan, liberal billionaire George Soros, former Attorney General Eric Holder, and Rep. Maxine Waters (D-CA). Thankfully, none of the devices have detonated.

The Department of Justice says to standby for a press conference this afternoon.

President Trump has reportedly been briefed on the arrest. He condemned the bomb threats earlier this week at a campaign rally in Wisconsin and from the White House, where he pledged to "bring those responsible for these despicable acts to justice.”
