Example Input: Sen. Elizabeth Warren  D-Mass.  said Thursday that the Democratic primary last year was "fair " moving away from the comments she made last week.

"We've got to hold this party accountable " she continued. "When Tom Perez was elected to chair of the DNC  the very first conversation I had with him was to say  'You've got to put together a Democratic Party in which everybody can have confidence that the party is working for Democrats rather than Democrats working for the party.'

But in this case  it was a security gap between the phone and the Web site that exposed strangers' Facebook pages to the Sawyers. Misconfigured equipment  poorly written network software or other technical errors could have caused AT
T to fumble the information flowing from the Sawyers' phones to Facebook and back.
T could confirm only that the problem occurred on one of the Sawyers' phones  possibly because they had logged off Facebook on the other two before reporting the incident.
 It's unclear how many people were affected by the problem the Sawyers discovered  and whether it was limited to Facebook.
 Usually that means a Web site simply won't load  said Alberto Solino  director of security consulting services for Core Security Technologies. In the Sawyers' case  "somehow they got the wrong user but they could keep using that account for a long period of time. That's what's strange " he said.
