The U.S. Supreme Court on Monday rejected a bid by anti-abortion activists to win the release of videos they surreptitiously recorded at meetings of abortion providers.

The justices declined to take up appeals by the abortion opponents and left in place a lower court's ruling blocking the release of videos that had the aim of exposing alleged illegal sales of aborted fetal tissue for profit. The trial judge in the case concluded there was no evidence of criminal wrongdoing by the abortion providers captured in the videos.

The activists, including anti-abortion group Center for Medical Progress founder David Daleiden, recorded the videos in 2014 and 2015 at annual meetings of the National Abortion Federation, a nonprofit organization representing abortion providers including affiliates of Planned Parenthood.
