Letter for President Obama contained Ricin
A letter addressed to His Excellency U.S. President Barack H. Obama was found to contain poisonous ricin, according to the Associated Press in Washington, which reported the matter after FBI authorities had conducted a positive test on it.
A day ahead, a letter addressed to Senator Roger Wicker had been confirmed to also contain ricin. Both letters were intercepted by responsible government officials before reaching their intended victims.
The report disclosed that the FBI failed to establish any connection to the bombings that happened in Boston Monday.
