PHOENIX (AP) - Authorities are investigating two suspicious letters that were sent to the Phoenix office of U.S. Sen. Jeff Flake of Arizona.



Emergency crews in hazardous materials gear rushed to the scene and evacuated people in parts of the building, located in the trendy Biltmore neighborhood of Phoenix.



Police spokesman Tommy Thompson says there were two suspicious packages and authorities are trying to find out if they are dangerous.



The situation came a day after authorities said a letter containing ricin was mailed to the office of a Mississippi senator. The Secret Service also says it has intercepted a

letter addressed to President Barack Obama

that contained a suspicious substance.



Flake is a Republican who was elected to the Senate last year.
