A new exit poll by Fox News found only 5 percent of New Hampshire Democrats viewed Hillary Clinton as "honest and trustworthy," while 93 percent of those asked picked her rival, Sen. Bernie Sanders, I-Vt.

Perceptions of Clinton on the question of honesty are worse in New Hampshire than they were in Iowa, where 10 percent picked her in an exit poll. Sanders was picked by 83 percent of those asked in Iowa about who is more honest.

The new numbers indicate the public's inability to trust the former secretary of state in the midst of an FBI investigation into her use of a private email server, a growing worry for many voters around the country.

Sanders is favored to win New Hampshire's first-in-the-nation primary Tuesday, according to the latest poll results.
