Former FBI / Weldon's Private Investigator Gregory Auld sings Auld Lang Syne

Digging a little deeper into the recent Delco Times story about Weldon's source for the leak about the investigation, something else is fishy. Seems that Weldon's former FBI agent source is a private investigator named Gregory Auld who has been paid $25,000 (so far) by Weldon's campaign.

So Weldon pays a PI for "Research" and he comes up with this?
From the Delco Times:

Weldon has charged that the investigation was timed to inflict maximum damage on his re-election campaign. Speaking to reporters after a House Aviation Subcommittee meeting Wednesday afternoon, he said the retired FBI agent, Gregory Auld, confirmed the night before that a Sestak worker "was bragging that three weeks ago they knew this was going to come down."

"That, to me, is absolutely outrageous," Weldon said. "If that occurred, it means that someone in the Justice Department was coordinating whatever was happening with a political campaign."

Except it didn’t happen, according to Auld, who told an entirely different story.

"No, that’s not what happened," he said in a phone interview, when asked about Weldon’s statements.

Auld, a retired FBI agent from Drexel Hill, said a man at a local gym - he refers to him as "Grumpy" because he doesn’t know his name - told him Tuesday that another man in a Sestak shirt said three weeks ago that "something big" would happen to Weldon last weekend. Auld then approached the Sestak supporter, who told him, "We kind of sniffed this out."

"I said, ‘You guys knew about this?’ and he didn’t say anything," Auld said, adding that it was the other man, "Grumpy," who said he had heard from the Sestak worker that "something big was going to come down on Weldon."

"He didn’t say, ‘We knew,’ he just said, ‘We sniffed it out,’" Auld said of his conversation with the latter individual.

First off, why didn't Weldon identify that his "source" was a private investigator that his campaign hired?
Second, why does Weldon even have a PI working on his campaign? What kind of bull is this? Sounds like typical Republican tried-and-wrong dirty tricks.
Third, Weldon paid $25K for a heresay report from a guy named "Grumpy" at a gym? Then his hired PI denies the story to the press? Is Weldon going to ask for a refund?
It all smells bad!

This latest contraversy is well-covered in Bill Bender's Delco Times article today too.

According to this page, the words "auld lang syne" can be translated to "times gone by" or "old long since". Hopefully, we'll look back on the work of Auld and say "times gone by" to Weldon's time in Congress in a few weeks.
