A photo of former presidential candidate Hillary Clinton glancing at a newspaper headline about U.S. Vice President Mike Pence using private email has gone viral on social media, with thousands of people commenting on it.

Pence and others involved in the Republican presidential campaign last year criticized Clinton's use of a private email server during her time as U.S. Secretary of State.

Clinton was on an airplane traveling from Boston to New York on Friday when a fellow passenger snapped a photo of her glancing down at Friday's USA Today newspaper front page headline "Pence used personal email in office".

Pence's use of an AOL email account was first reported by the Indianapolis Star on Thursday. It said Pence used the account, which was hacked last summer, at times to discuss sensitive matters and homeland security issues while he was governor of Indiana.
