Hillary Clinton projects invincibility, so it was shocking to many that she fainted today and suffered concussion. She's now resting to recover from her fall and the case of stomach flu that caused her to faint.
Since she's unwell, Clinton has pulled out of testifying in the Senate Foreign Relations Committee's hearing next week on the 9/11 Benghazi attack.
Hillary's withdrawal may spur conspiracy theories and speculations that her fainting fit was staged to avoid the hearing. But it's utterly plausible that she's simply under the weather. Being Secretary of State is allegedly the most exhausting job in America - some say even more so than being president.
Apparently she is being treated by doctors, and hasn't been hospitalized.
