Supreme Court Temporarily Blocks House From Viewing Mueller Materials

The transcript discusses the Department of Justice's (DOJ) request to the Supreme Court to pause a lower court's ruling requiring the release of secret grand jury information from Robert Mueller's Russia investigation to Congress. The House Judiciary Committee seeks these materials to investigate potential obstruction of justice by the president, as Mueller's report did not address this. The DOJ argues that grand jury materials should only be released for judicial proceedings, not legislative ones. The department has until June 1st to appeal the decision.

What argument did the Justice Department make regarding judicial proceedings?

What will happen if the High Court denies the appeal?
