"It's sort of shocking to me who's coming through and who's not" for donations, McCord told one of his targets in a conversation apparently recorded by federal agents or cooperating witnesses, the records show. "At the very least, I'm still gonna be the freakin' treasurer."
The documents didn't offer details about the origin of the FBI investigation, name his alleged victims, or say whether they gave him the money he sought.
But they added substance to what for days had been speculation and, for the first time, offered an unvarnished glimpse of the threats and conduct that last week toppled the 55-year-old Democrat from office.
McCord, a former venture capitalist from Bryn Mawr, apologized Friday in a video statement released by his Philadelphia lawyer, Robert Welsh. The former treasurer also said he would plead guilty. His plea hearing is set for Feb. 17.
In a statement Monday, FBI Special Agent in Charge Edward J. Hanko, who heads the Philadelphia division, said: "The citizens of the commonwealth expect and deserve public officials who perform their duties free of deceit, favoritism, bias, self-enrichment, concealment and conflict of interest."
The charges stem from McCord's bid last spring to raise money for the four-way race for the Democratic nomination for governor.
At the time, Tom Wolf had become the unexpected front-runner, having launched a series of early and successful television ads, and after pouring millions of his own money into the campaign.
McCord spent $2 million of his own on his candidacy but wasn't getting traction. By spring, he appeared desperate for an edge, according to snippets of his conversations. Those details and others were outlined in a "joint statement of facts" about the case that McCord and prosecutors signed Thursday and made public Monday.
In April and May, it said, he targeted a Philadelphia law firm for a $25,000 campaign donation. Pennsylvania law places no limits on individual campaign contributions.
One of McCord's neighbors was a lawyer at the firm, prosecutors allege, and the treasurer had urged the lawyer to "browbeat" the firm's managing partner - a financial backer of then-Gov. Tom Corbett - into allowing the lawyer to make a sizable contribution to McCord.
In one April 21 conversation, McCord coached the attorney to tell the managing partner that he could hurt the firm, which has multiple state contracts, including with the Treasury, if it did not make a sizable contribution:
"And that's fine, but you also run a law firm, so if you are not going to hedge your bet, don't think that I am so stupid that I am not going to read you the riot act down the road. You know what I mean?"
In a conversation with the managing partner a week later, McCord said that letting the lawyer be a conduit for the donation would shield the firm from exposure. The firm could then "somehow give credit" to the lawyer for the contribution.
"We're all free and clear, nobody's in trouble, and you guys have been there for me," McCord told the managing partner, the documents show.
Around the same time, McCord directed one of his campaign "bundlers" - who solicit contributions from friends, business associates, and others - to squeeze a Western Pennsylvania property management firm for $100,000.
In a telephone conversation with the bundler, McCord complained that the principals of the property management firm were "rich as gods," and urged the bundler to call them and say things that "I don't want to say."
The firm had received benefits and other incentives from the state that were approved in part by McCord.
The documents say McCord counseled the bundler to "get them learning" that as treasurer, McCord was a "fiscal watchdog" - the inference being that he could stop state benefits from flowing to the company.
Aside from managing the state's money, the treasurer is a key investor of state dollars. McCord told the bundler to convey that the campaign contributions didn't need to be in the company's name.
"You can kind of say, 'Look, you guys, Rob will be fine with the checks not coming in your name. I can tell him that this is from you,' " McCord admitted telling the bundler. "But what doesn't work is you turning a friend into an enemy by breaking your word."
The maximum penalty for each extortion count is 20 years in prison and a fine of up to $250,000, though McCord would be likely to face a far lighter sentence.
His lawyer, Welsh, stressed Monday that McCord was not looking to enrich himself. He also said McCord immediately confessed after being confronted by agents in December.
"I think it's very important to examine the facts of what he's pleading to here," Welsh said. "It's not putting millions of dollars in his own pocket by selling his office. He's pleading guilty to crossing the line in fund-raising."
In announcing the charges, officials said Peter Smith, the U.S. attorney in Harrisburg, had to recuse himself from the case because he once worked for McCord at the Treasury.
Instead, the case was overseen by First Assistant U.S. Attorney Dennis C. Pfannenschmidt.
"Public corruption cases are some of the most serious cases our office handles, and this case indicates a serious breach of the public trust," Pfannenschmidt said in a statement. "Our office is committed to working with our law enforcement partners in holding public officials responsible for their violation of the public trust."
