It is unclear if the Democrats are attempting to force this investigation as cover against the Russia probe origin investigation being conducted by US Attorney John Durham.
The Supreme Court temporarily denied a motion Wednesday from House Democrats to obtain grand-jury testimony and other documents from former Special Counsel Robert Mueller's Russia investigation as they conduct what they've referred to as an "ongoing presidential impeachment investigation" into President Trump.
The court's order kept undisclosed details from the probe into Russian interference in the 2016 presidential election out of the Democrats' hands until at least early summer. Democrats have until June 1 to brief the court about whether the full case should be heard.
The Democrats had told the court Monday they were in an "ongoing presidential impeachment investigation" while arguing that Mueller's now-completed Russia probe needed to be turned over as a result.
"The [House Judiciary] Committee’s investigation did not cease with the conclusion of the impeachment trial," the Democrats told the nine justices. "If this material reveals new evidence supporting the conclusion that President Trump committed impeachable offenses that are not covered by the articles adopted by the House, the committee will proceed accordingly — including, if necessary, by considering whether to recommend new articles of impeachment."
