WASHINGTON — The Supreme Court on Wednesday agreed to hear an appeal brought by a man charged with offenses relating to the Jan. 6, 2021, assault on the U.S. Capitol in a case that could have a major impact on the criminal prosecution of former President Donald Trump.

The justices will hear a case brought by defendant Joseph Fischer, who is seeking to dismiss a charge accusing him of obstructing an official proceeding, namely the certification by Congress of President Joe Biden's election victory, which was disrupted by a mob of Trump supporters.

Two other Jan. 6 defendants, Edward Lang and Garret Miller, brought similar appeals, the outcome of which will be dictated by the Supreme Court's ruling in Fischer's case.
