HILLARY CLINTON has secretly decided to run for president in 2016, but doctors have warned that pursuing her dream of becoming America’s first female commander in chief could kill her!

In a bombshell world exclusive, The ENQUIRER has learned Hillary wants to spurn her doctors’ advice and announce her candidacy on June 4, 2014 – the day her late mother would have turned 95.

Sources say the 66-year-old former first lady and her husband Bill are already laying the groundwork to build a $5 BILLION war chest to fund her campaign, with their daughter Chelsea playing a major role.

But after surviving a string of devastating medical crises, Hillary remains haunted by her historic decision, and insiders say anxiety over her well-being could derail her candidacy.

“Hillary’s doctors have painted a grim picture of her health,” said a close source. “Behind the scenes, they’re telling her, ‘Running for president will kill you.’

But Hillary wants to ignore her doctors because she’s so desperate to be America’s first female president.

“She believes it’s what she was put on earth to do, and there’s no convincing her otherwise.

“But Bill, who has wrestled with severe health issues including several heart operations, is telling Hillary that they need to think long and hard about this.”

As The ENQUIRER has reported, former secretary of state Hillary has struggled with a number of health concerns. She faced a brain cancer scare after a faint- ing spell resulted in a concussion in December 2012.

Following extensive testing, doctors discovered a blood clot in a vein between Hillary’s brain and her skull behind her right ear. The dangerous clot was dissolved with blood thinners during a frightening hospital stay.

She also fainted while speaking in Buffalo, N.Y., in 2005. In 2009, she broke her elbow in a fall in the State Department garage, and in January 2011 he collapsed while boarding a flight in Yemen.

Dr. Jerome Spunberg, a radiation oncologist and medical expert in West Palm Beach, Fla., who has not treated Hillary, suspects she may have under- lying medical issues.

“The blood clot and fainting spells reveal that she is not in the best of health,” Dr. Spunberg told The ENQUIRER. “She’s probably suffering from some form of cardiovascular disease that may be causing dangerous changes in blood pressure and a tendency to develop blood clots. As she gets older, the pressures of running for office – and, if she wins, assuming the presidency – can increase her risk of heart attack, stroke and other deadly diseases.”

Dr. Gabe Mirkin, author of “The Healthy Heart Miracle,” who has not treated Hillary, says he’s noted “a radical change” in her, and believes the truth about her medical condition has been withheld from the public.

“In the past, she was an incredibly vigorous woman who experienced many stressful situations without succumbing to health issues,” Dr. Mirkin told The ENQUIRER. Despite doctors’ warnings, Hillary decided to run for president after a heart-to-heart talk with Bill around their 38th wedding anniversary on Oct. 11, a political insider told The ENQUIRER.

“Hillary will likely defy her doctors and announce her candidacy on June 4, which would have been her mother Dorothy’s 95th birthday,” a family insider told The ENQUIRER.

“Hillary simply cannot be stopped. Even when she was suffering from the blood clot near her brain, she told Bill and Chelsea that she was intent on raising a ‘$5 billion war chest’ for her campaign. “They tossed out names of possible supporters while Hillary was still in her hospital bed.”

The Hillary-for-President bandwagon has already attracted big-bucks donors, including 
billionaire investor Warren Buffett, market
 speculator George Soros and director Steven Spielberg and his wife Kate Capshaw.

Chelsea, 33, will play a significant role in the campaign, but without her husband, Marc Mezvinsky, said a source.

“Bill and Hillary are intent on Chelsea having a baby soon, and then having Chelsea campaign with the baby,” said the source.

“They believe Chelsea’s presence as a new mom will attract young female voters. That’s not going to sit well with Marc, who’s continually felt frozen out by the Clintons. But Chelsea will do whatever she can for her mom. She’s a Clinton first and a wife second.”

The political insider added: “Having Chelsea and the baby involved will make the family look younger and give a Kennedy-like ‘Camelot’ touch to the campaign.”

Meanwhile, former president Clinton, 67, is working feverishly to put his wife in the Oval Office, said the source. “Bill has visited nearly every state in the union, recruiting rich donors, political supporters and volunteers,” the political insider told The ENQUIRER.

“As badly as Hillary wants to get back into the White House, Bill wants it more. It would be like a third term for him and give him a chance to build on his presidential legacy.”

It would also give the Clintons the opportunity for payback with President Barack Obama, said the source.

“Hillary felt she deserved the nomination five years ago, and Barack stole it right out from under her,” said the insider. “Ever since then, a Clinton-Obama feud has been simmering right below the surface.

“With the president and Democrats going up in flames over the Obamacare fiasco, Bill told Hillary, ‘You have to save America.’
