Suspected to Contain Cyanide, Letter Addressed to White House Ordered Further TestingA third round of testing has been ordered to ascertain whether an envelope addressed to the White House really contained cyanide. As per the Secret Service, initial testing had shown the result as negative, but a subsequent test had been “presumptive positive” for cyanide. An infrastructure situated at a distance from the White House and its precincts, had received the letter on Monday, and had sent it for a routine screening. On not being fully satisfied with the first two tests, the letter had been sent for the third testing.

The Secret Service of the U.S. which holds the responsibility for the security and safety of the President Barack Obama and his immediate family members, told that further investigations on the letter had been going on, and it would not like to comment additionally on the matter. Suspicious letters have often been sent to many influential politicians including the President of the country. Many of these letters tested positive for poisonous and hazardous substances while some others contained threats of death and other physical injuries. Some of the letters addressed to Obama, Roger Wicker, Sen, and Sadie Holland, Mississippi Judge, in 2013, had tested positive for a poison called ricin. The letters sent to the President and others had been intercepted prior to their delivery except the one addressed to Holland, which reached her, but, luckily, she had escaped unhurt. A person named James Everett Dutschke, belonging to Tupelo, Mississippi, had admitted his guilt, in 2014, of sending such letters, and the court awarded him the punishment of imprisonment for 25 years.
