Thirty U.S. service members were killed on August 6, 2011, when a CH-47 Chinook was shot down in Afghanistan's Wardak province. As Gateway Pundit’s Jim Hoft reminds us, it is the deadliest single loss of U.S. forces in the Afghanistan campaign.

Among those killed in the crash were 17 members of the U.S. Navy SEALs. And although the deadly attack was over a year ago, it wasn’t until yesterday that, apparently, parents of fallen SEALs revealed that were sent stock letters with President Obama’s electronic signature.

"Yesterday, Karen and Billy Vaughn, parents of Aaron Carson Vaughn, spoke at the Defending the Defenders forum sponsored by the Tea Party Patriots outside the RNC Convention in Tampa. Karen brought a copy of the form letter they were sent following their son’s death," Hoft reports.

A form letter?

But wait. There's more.

“Karen Vaughn reached out to the parents of the other SEALs killed in that crash,” Hoft adds. “Their letters were all the same. Form letters -- signed by an electric pen.”

After a closer inspection of the letter sent to the parents of Chief Petty Officer Nicholas H. Null, it would appear that it’s exactly the same as the others:

"After the deadliest single loss of US forces in Afghanistan, Barack Obama sent out form letters to the parents," Gateway Pundit’s Jim Hoft writes.
