Mary Lou Mezzatesta, who was in Romney at the time, also called Howard and said she "had never seen [her husband] so mad" and that "she could not calm Jerry down," according to the report.
Later, Mary Lou Mezzatesta told her, "We are going to have to type the letter. Can you handle this?" Howard told investigators.
That same day, Mezzatesta called the employee and directed her to file a copy of the letter in Delegate Larry Williams' office, Howard told investigators. Williams is vice chairman of the House Education Committee.
Mary Lou Mezzatesta later ordered Howard to put copies of the fabricated letter in file cabinets throughout the House Education office, according to the report.
She also directed Swagger to download numerous documents onto her House office computer, "delete them, then periodically defragment the drive, repeating the process more than once," Swagger told investigators.
"Mrs. Mezzatesta stated that she received advice on this process from relatives with degrees in computer science," according to the report.
Investigators never found an electronic copy of the fake letter.
Howard and Swagger initially lied to Kiss and investigators, but later detailed the scheme, according to the report.
Howard said she felt "compelled to lie" at one point because Mezzatesta and his wife were in the room when she first met with Kiss.
The two women said they received repeated calls from Mezzatesta and his wife. Mary Lou Mezzatesta also came to her house late at night, informing her "what Mrs. Mezzatesta's story was going to be, which was that Delegate Mezzatesta knew nothing about the creation of the letter."
Mary Lou Mezzatesta repeatedly called her husband during the late-night visits, the women said.
According to the report, Lindroth, Mezzatesta's lawyer, delivered copies of the fabricated letter to Stewart, Clifford and the Ethics Commission on July 1.
Lindroth, who also serves as Kiss' lawyer, told investigators that he didn't know the letter was a fake.
Two House computer technicians told investigators that Lindroth peppered them with questions about deleting and recovering files from a computer after the Gazette requested his computer files last summer.
Investigators also interviewed Williams, who has told Ethics Commission lawyers and the media that Mezzatesta's fabricated letter is authentic.
When asked if Mezzatesta had asked him to concoct a story related to the letter, Williams told investigators, "No. I don't think he'd do that."
Kiss declined to answer questions during Thursday's press conference.
House officials would not say whether disciplinary action would be taken against Mary Lou Mezzatesta and the other state employees.
Delegate Bonnie Brown, D-Kanawha, said Mezzatesta's actions have "tainted" the Legislature.
"This has been trying not only for the speaker, but for all of us," Brown said Thursday.
Meanwhile, state GOP Executive Director Gary Abernathy called the House employee statements against Mezzatesta "devastating." He said Kiss should recommend that Mezzatesta be impeached.
"The letter was a fake, and Mezzatesta lied," Abernathy said. "But I've heard nothing from the speaker beyond, 'I'm sorry.' "
