A Pew Research Center survey of U.S. journalists found that more then half believe the government has spied on their telephone calls and emails, the Washington Examiner has learned.

A survey of 454 members of the group Investigative Journalists and Editors found that 64 percent believe the Obama administration at one point monitored their phone conversations, emails and Internet searches.

The survey comes two years after whistleblower Edward Snowden exposed secrets of NSA spying on citizens' phone and Internet records to The Guardian and other newspapers.

Also, last week The NY Times reported that the Obama administration in 2013 snooped through the call records of Associated Press reporters, and the government did not give a viable explanation for it, the Times reported.

Eight out of 10 survey respondents said they fear their profession makes them a more likely target of surveillance.

Most journalists, however, said their spying suspicions did not deter them from doing their jobs.

"Just 14 percent say that in the past 12 months, such concerns have kept them from pursuing a story or reaching out to a particular source, or have led them to consider leaving investigative journalism altogether," the survey reads.

If anything, the alleged government spying has motivated reporters to come up with new covert ways to gather information.
