She said she isn't sure why people would allege that her husband had anything to do with firing Marple. She said blogs and social media makes it easier to say or publish ideas without first verifying statements.
"I don't understand people that operate that way, that without any shred of evidence just make outlandish statements," she said. "I can't tell you why people do that."
A representative for Sen. Manchin said he was unavailable for a phone interview Monday, but emailed a statement that said he had no involvement in Marple's dismissal.
Last week, board President Wade Linger called the allegations of a Manchin faction on the board "bulls - - t."
Former board member Lowell Johnson said last week that he assumed Gayle Manchin is the major leader on the board because her husband appointed all those who voted to fire Marple.
Johnson said Monday he wasn't sure why Marple was fired and he didn't "want to get into" the political aspects of the decision.
"I'm going to hope the motive of the five who did this was pure in nature, although I have a big question mark in my mind," Johnson said.
