The democratic nominee cancelled her appearance at the Masonic after becoming sick on Sunday. She was diagnosed with pneumonia on Friday.
Her campaign is now being criticized for an apparent lack of transparency.
Video form Sunday shows Hillary Clinton stumbling while trying to get into a van has many wondering why her campaign waited two days to reveal she had pneumonia.

"If your challenge is transparency, that's a problem," said Ken Goldstein, Professor of Politics at USF.
Goldstein says it hurts her campaign when Hillary becomes the story. Republicans are once again questioning her honesty.
"It's standard procedure to withhold information. I mean they've been in the business for years and they keep a lot of secrets," said Jason Clark with the San Fran cisco Republican Party.
"Both candidates have not come forward with information about their health as much as the public deserves," explained ABC7 News Political Analyst and Politico Correspondent Carla Marinucci.
After the episode both candidates have vowed to release their personal health information.
Some believe not every flu, pneumonia or cold should be reported. Only serious, debilitating conditions should be disclosed by a candidate. For example, John McCain had several bouts with skin cancer. During the 2008 presidential campaign, he had to release his medical records.
Goldstein says the public should realize campaigning is grueling work.
"It is brutal and you have to be on all the time, all the time and it takes a toll," said Goldstein.
