It's the conspiracy theory whirling around Hillary Clinton's People magazine cover. What's that her hands are resting on?

Twitter exploded with the suggestion that it's a walker.

There's been concern about Hillary's health since she was hospitalized after a fall in late 2012. The official diagnosis was a concussion and blood clot. But critics like Republican strategist Karl Rove have had a field day.

Rove said, "We don't know what the doctors said she has to be concerned about. She's hidden a lot."

Now, People magazine is putting the walker conspiracy theory to rest. "It's a chair" the magazine tweeted. And to prove it, they released a full-sized photo from the shoot that reveals it to be a chair, not a walker.

Posing with a chair turns out to be a Hillary trademark. She did the same thing in her first solo People cover from back in 1993.

Now, this conspiracy theory is officially over.
