The white powder sent to Rep. Anthony Weiner's office appears to be a kind of antacid. The powder—which forced nine staffers at the Congressman' Kew Gardens office to be decontaminated yesterday—was harmless, Police Commissioner Ray Kelly told the Daily News. "That was the initial finding, and it'll be confirmed in a lab."

Kelly told the tabloid that the letter said "something about health care," as well as "some derisive comments about Congressman Weiner." The letter reportedly urged the health care reform supporter to: "Sniff this and you'll see." Kelly said he has dispatched officers to speak with staff for all of the city's Congressional delegates. "Every entity, their office, has been visited, though the principals may be in Washington. We've told them if there are any issues, they should call."

Weiner has said he was troubled by the fact his staff was targeted, and he blasted former Alaskan Governor Sarah Palin for sending out a Tweet that he claims could be interpreted as a call to arms.
