(NOTE: With the Clinton campaign announcing Hillary was diagnosed with pneumonia on Friday, reporter David Martosko is owed an apology from Clinton’s Traveling press Secretary Nick Merrill and Adam Parkhomenko, a former Clinton aide and current Democratic Party operative, who attacked Martosko online and threatened his job for expressing his observation that Clinton appeared “low energy” at a late Friday afternoon press conference on national security issues.)

The campaign of Democratic Party presidential nominee Hillary Clinton released a statement from her doctor stating Clinton was diagnosed with pneumonia on Friday.

“Statement from Dr. Lisa R. Bardick, M.D. “Secretary Clinton has been experiencing a cough related to allergies. On Friday, during follow-up evaluation of her prolonged cough, she was diagnosed with pneumonia. She was put on antibiotics, and advised to rest and modify her schedule. While at this morning’s event she became overheated and dehydrated. I have just examined her and she is now re-hydrated and recovering nicely.”

Ill health forced Clinton to leave the commemoration in New York City Sunday morning marking the 15th anniversary of the 9/11 attacks.

Clinton was seen on video being propped up by a curbside bollard while an aide held her arm as a Secret Service vehicle pulled up.

Clinton seized up and fell as her foot caught the sidewalk while Secret Service agents struggled to assist her to take the few steps to the waiting vehicle. A mysterious object was filmed apparently dropping from Clinton’s right pant leg as she collapsed.

A few hours later a smiling Clinton told the press she was feeling “great” as she left her daughter Chelsea’s apartment after having been taken there from the 9/11 ceremony.

Clinton then headed to her home in Chappaqua, New York to rest.

Signs of Clinton’s unannounced illness were witnessed on Friday. In addition to her “low energy” appearance noted by David Martosko, at the end of her press conference Clinton ducked behind a pillar to keep the press from filming her having a brief coughing fit.

A subdued Clinton had to keep pausing mid-sentence to breath during the taping Friday of an interview with CNN’s Chris Cuomo.
