The announcement by the White House comes days after the petition gained a record half a million signatures, five times the number needed to get a response from the Obama Administration.

"Closed petition", said the petition page. "This petition has been archived because it did not meet the signature requirements. It can no longer be signed," the White House explained.

No further explanation has been given by the White House on closing the petition for signature. Normally it is open for a month for the people to sign. However, it looks like that some of the signatures might not have had met the terms of participation for these petitions.

As a result, it is very well possible that some of these signatures could be removed if there is evidence of fraud. But the White House is expected to have an official response to the petition within the 60 days deadline.

The petition was created on September 21 by a person who identified himself by initials RG and the petition needed 1,00,000 signatures in 30 days to get a response from the White House.

The benchmark was reached in less than a week, and in less than two weeks, the petition crossed half a million signatures.

The petition comes after Congressman Ted Poe, Chairman of the House Subcommittee on Terrorism, along with Congressman Dana Rohrabacher, introduced H R 6069, the Pakistan State Sponsor of Terrorism Designation Act in the House of Representatives.
