NEW Duggar Sex Scandal! Disgraced Josh Reportedly Caught Watching Porn On Work Computer— Two Years After Allegedly Molesting Sisters

Christian dad Josh Duggar allegedly has even more dirty sex secrets he's desperate to keep quiet.

While working on a campaign for an Arkansas politician in 2004, Jim Bob and Michelle's disgraced eldest son, now 27, was accused of watching porn on company computers, In Touch reports.

"The politician lost the election— and full blame was put on Josh," a church insider tells the magazine.

Though Josh's shocking behavior did not go public, the source explains, the politician assumed he lost due to "sins in the camp," or deviance within his own team.

"That's when Josh's activities were discovered," the source reveals.

According to insiders, Josh, who was 16 at the time, was reprimanded with a "very serious punishment" from church elders.

As RadarOnline.com readers know, just two years before this scandal, police claim Josh fondled five minor females in the 19 Kids And Counting clan's home.

In a recent TV interview, Josh's younger sisters Jessa, 22, and Jill, 23, came forward as two of his innocent victims.

In the aftermath of the police report revelations, the father of three resigned from his position at a conservative lobbying organization the Family Research Council, and moved from Washington, D.C., back to his home state of Arkansas in shame.
