Parsons wrote in her letter that she had worked for Mueller as a paralegal at the Pillsbury, Madison, and Sutro law firm in 1974, but that she “didn’t see” him much. “When I did see him, he was always very polite to me, and was never inappropriate,” she said. The law firm told me late on Tuesday afternoon, however, that it has “no record of this individual working for our firm.”

Parsons explained that she was contacted by a man “with a British accent” who wanted to ask her “a couple questions about Robert Mueller, whom I worked with when I was a paralegal for Pillsbury, Madison, and Sutro in 1974. I asked him who he was working for, and he told me his boss was some sort of politics guy in Washington named Jack Burkman. I reluctantly told [him] that I had only worked with Mr. Mueller for a short period of time, before leaving that firm to have my first son.”

She continued: “In more of an effort to get him to go away than anything else, I asked him what in the hell he wanted me to do. He said that we could not talk about it on the phone, and he asked me to download an app on my phone called Signal, which he said was more secure. Reluctantly, I downloaded the app and he called me on that app a few minutes later. He said (and I will never forget exactly what it was) ‘I want you to make accusations of sexual misconduct and workplace harassment against Robert Mueller, and I want you to sign a sworn affidavit to that effect.’” The man “offered to pay off all of my credit card debt, plus bring me a check for $20,000 if I would do” it, she wrote. “He knew exactly how much credit card debt I had, right down to the dollar, which sort of freaked me out.”

Surefire Intelligence was incorporated in Delaware less than three weeks ago, according to online records, and describes itself as “a private intel agency that designs and executes bespoke solutions for businesses and individuals who face complex business and litigation challenges.” Surefire’s domain records list an email for another pro-Trump conspiracy theorist, Jacob Wohl, who began hyping a “scandalous” Mueller story on Tuesday morning. Wohl told The Daily Beast that Burkman had hired Surefire to assist with his investigation into Mueller’s past, but denied knowing anything about the firm’s involvement in an alleged plot to fabricate allegations against Mueller when asked why his email address appeared in the domain records. He did not respond when asked by NBC why a telephone number listed on Surefire’s website referred callers to another number that’s listed in public records as belonging to Wohl’s mother.

Parsons was not willing to speak to the reporters by phone, according to Scott Stedman, one of the reporters who received the letter. So portions of her story have gone uncorroborated, and her identity has not been independently confirmed.
