House of Representatives investigators are looking into whether President Donald Trump lied to special counsel Robert Mueller during the Russia probe.

"Did the president lie?" a House lawyer said in court as he requested files from the special counsel's inquiry.

Congressional impeachment lawmakers are reportedly scrutinising the president's statements to Mr Mueller on WikiLeaks.

The main thrust of the Democratic-led inquiry is on alleged abuse of power by Mr Trump in US-Ukraine relations.

Lawmakers first requested classified grand jury materials from the report in July.

A judge in October granted this access, though the Department of Justice appealed. Monday's hearing was to determine whether the appeal should temporarily block the previous grant of access.

Congress has seen most of the Mueller report - including some redacted parts - but certain grand jury material has remained secret.
