PHILADELPHIA - Donald Trump's sister, Maryanne Trump Barry, will not be a part of a federal appeals court panel hearing arguments regarding the release of a list of unindicted co-conspirators in the 2013 Bridge-Gate lane-closing scandal.

The 3rd U.S. Circuit Court of Appeals in Philadelphia delayed the release of the list on Tuesday and set a June 6 hearing.

The court announced Wednesday that judges Thomas Ambro, Kent Jordan and Anthony Scirica will hear 15 minutes of arguments from a group of media organizations and from a lawyer representing an anonymous person on the list seeking to block its release.

Two former allies of Republican Gov. Chris Christie have been indicted and face trial this fall. A third pleaded guilty.

Maryanne Trump Barry is one of the 24 judges on the 3rd Circuit.
