President Donald Trump suggested Wednesday he might use his executive authority to intervene in a fight over internal Justice Department documents sought by House Republicans, including some related to the Russia probe.

"A Rigged System — They don't want to turn over Documents to Congress," Trump tweeted. "What are they afraid of? Why so much redacting? Why such unequal 'justice?' At some point I will have no choice but to use the powers granted to the Presidency and get involved!"

House Republicans have criticized the Justice Department for not providing a broad cache of documents as promptly and completely as they requested. Some of the documents relate to the origins of the investigation into possible collusion between Trump's campaign and Russia during the 2016 election; others pertain to the FBI inquiry into Hillary Clinton's use of a private email server.
