DOCTORS have admitted Hillary Clinton to hospital after she developed a blood clot resulting from the concussion she suffered last month.
Mrs Clinton, who is due to step down as Barack Obama's Secretary of State this month after what is widely viewed as a successful tenure as America's most-travelled senior diplomat, was asked to stay at New York Presbyterian Hospital when the clot was discovered during a medical examination.
The health scare is bound to raise questions about her health and ability to contest the next race for the White House.
What should have been a routine check-up had been planned after Mrs Clinton (65) fainted and hit her head in mid-December while suffering from dehydration caused by a stomach virus.
A spokesman for the State Department said doctors were treating Mrs Clinton with anti-coagulants and would keep her in hospital for 48 hours for monitoring.
Though there was no suggestion of any serious medical developments, her health has come into focus as attention turns from her tenure at the State Department to a potential White House run in 2016.
Over the past four years she has maintained a gruelling schedule and broken the record for a US Secretary of State by visiting 112 countries.
She was also unable to testify before a Congressional panel investigating the attack on the US diplomatic mission in Benghazi, Libya. The assault on September 11 led to the deaths of a number of US officials, including the ambassador to Libya Chris Stevens and provoked a heated debate between the White House and Republicans, who questioned security arrangements for US diplomats abroad.
A report concluded that the State Department's decision to keep the Benghazi outpost open, despite "the inability of the Libyan government to fulfil its duties to secure the facility" and "the increasingly dangerous threat assessments", was a "grievous mistake". The report, by the Senate Homeland Security Committee, also criticised US intelligence agencies for not according enough focus to Libyan extremist organisations.
Mrs Clinton is due to be replaced by John Kerry, the veteran Massachusetts senator and 2004 presidential candidate, at about the time of Mr Obama's second inauguration on January 20. (©Independent News Service)
