The Washington, D.C. headquarters of the Republican National Committee was placed in lockdown on Wednesday morning after vials of blood were sent to the building, reports say.
A hazardous materials unit with the U.S. Capitol Police traveled to the site after a suspicious package was found. A police source told CNN that it contained the blood along with two ice packs and a Korean Bible.
The network said that an all-clear was given at the site just after 9 a.m. local time. One source who spoke with NBC News said the blood is now being tested.
