According to Colonel Earl Matthews, who testified before Congress in April, US military leaders revoked President Trump’s Commander-in-Chief powers that day and refused to move in the National Guard – because it might look bad.

These military leaders should have been arrested and court martialed.

Donald Trump’s authority as commander-in-chief was ignored by senior military leadership on January 6, 2021, claims the chief legal advisor for D.C. National Guard on that day.

Colonel Earl Matthews came forward as a whistleblower to the House subcommittee reviewing the January 6 Select Committee’s investigation.

He sat down with DailyMail.com two weeks after the public hearing to explain what he saw happen that day.

He claims that Mark Milley, Chairman of the Joint Chiefs of Staff at the time, and then-Army Secretary Ryan McCarthy, were plotting to disobey any orders handed down by Trump because they ‘unreasonably’ assumed the then-president was going to break the law and try to use the D.C. National Guard (DCNG) to stop certification of the 2020 presidential election results.

A lot has been made about the breakdown in military and administration communication when it came to the timeline of deploying DCNG to the Capitol.

But Matthews claims senior military leadership was solely focused on getting the heat off of them and putting it back onto Trump.
