'Urgent' Hill briefing on Ukraine comes as impeachment inquiry speeds ahead edition.cnn.com

The impeachment inquiry that has pitched Donald Trump's presidency into its deepest-ever crisis took a new twist after the independent inspector general from the State Department asked for an "urgent" briefing with congressional committees about documents related to the Ukraine scandal.
A congressional aide described the request for Wednesday's briefing as "highly unusual and cryptically worded."
The dramatic development came after Secretary of State Mike Pompeo attempted to prevent witnesses linked to his department from appearing on Capitol Hill in the coming days. The move appeared to be an attempt to buy time to come up with a long term blueprint to save Trump by turning the politics of impeachment.
