'Like anyone who's ever been home sick from work, I'm just anxious to get back out there. See you on the trail soon,' she wrote on Twitter
Democratic presidential candidate Hillary Clinton said on Monday she was "feeling fine", a day after she had to leave September 11 remembrance ceremony due to 'overheating'.
Clinton said on Twitter, "I'm feeling fine and getting better.”
"Like anyone who's ever been home sick from work, I'm just anxious to get back out there. See you on the trail soon," she added.
Meanwhile, Clinton's campaign acknowledged mishandling of news of her pneumonia, Guardian reported today.
“We could have done better yesterday,” Clinton communications director Jennifer Palmieri was quoted as saying.
Clinton fell ill during a memorial service marking the 15th anniversary of the September 11, 2001 terror attacks.
She was seen stumbling as she was helped into her vehicle, forcing her campaign to disclose she had been diagnosed with pneumonia.
The incident gave her rival Donald Trump, 70, a new opening to question her fitness for the nation's highest office.
Trump, reacting to Clinton's pneumonia news, has pledged to release his medical records insisting that health has now become an issue in the election campaign.
Clinton canceled a trip she was scheduled to take to California on Monday and Tuesday for fundraising and other campaign events.
Clinton's husband, Bill Clinton, will be "campaigning in Nevada on the secretary's behalf on Wednesday," an aide to the former president said in a statement released by the campaign.
