Former U.S. Secretary of State Hillary Clinton has been caught intently looking at a newspaper story about Vice President Pence's email issues, according to local media reports.
While sitting in a Boston-to-New York flight, Clinton was caught by a passenger to be glancing at a front-page story in USA Today "Pence used personal email in office."
The photo posted on the passenger's Twitter acount was quickly and widely circulated.
Clinton's 2016 Democratic presidential bid was mired in her use of private email server to send and receive official State Department information.
An FBI investigation concluded that Clinton's actions were "extremely careless" but not criminal.
Pence used his email account, which was hacked last summer, at times to discuss sensitive matters and homeland security issues when he was governor of Indiana, the Indianapolis Star reported on Thursday.
"I am very confident our email practices were in compliance with Indiana's laws," Pence told reporter Friday in Wisconsin.
He also said there is "no comparison whatsoever" between his situation and Clinton's, considering she "mishandled classified information" and "destroyed" email requested by members of Congress and other officials.
