• Former "19 Kids and Counting" star Josh Duggar's trial is set to start Tuesday in federal court.
• The 33-year-old was charged with two felony counts of receiving and possessing child pornography.

Former "19 Kids and Counting" star Josh Duggar is set to face trial in federal court on Tuesday on two felony child pornography charges that could see him spending up to four decades behind bars if he's convicted.

The 33-year-old was arrested on April 29, and prosecutors alleged he "used the internet to download child sexual abuse material," some of which depicted children under the age of 12. His official charges are receiving and possessing child pornography.

For first-time offenders, both charges carry a maximum sentence of 20 years in prison and fines of $250,000, according to the United States Sentencing Commission.

Duggar has pleaded not guilty to both of the charges.

Jury selection in the trial starts on Tuesday. The trial, which is being held in Fayetteville, Arkansas, will not be televised.

A hearing was scheduled for Monday, during which the judge was expected to rule on what kind of evidence could be used during the trial.

Prosecutors want to bring up prior allegations that Duggar molested four of his sisters when he was a minor. Duggar was never charged with a crime in connection to the molestation allegations, and his legal team is fighting to ban the allegations from being mentioned during the trial, according to local outlet KNWA/Fox 24.
