Donald Trump is publicly considering firing Special Counsel Robert Mueller, the person leading the Department of Justice investigation of possible criminal actions by Donald Trump and members of his presidential campaign, as well as the efforts to conceal those activities.

It’s also possible that, rather than firing Mueller, Trump will obstruct Mueller’s investigation by issuing blanket pardons of key figures being investigated, firing Deputy Attorney General Rod Rosenstein (the person overseeing Mueller), or taking other actions to prevent the investigation from being conducted freely.

Any one of these actions would create a constitutional crisis for our country. It would demand an immediate and unequivocal response to show that we will not tolerate abuse of power from Donald Trump.  If Trump takes any of these actions, demonstrations are planned across the country.  Our demonstration site is Representative Elijah Cummings’ Catonsville Office, Catonsville, MD 21228

If any of these actions occur BEFORE 2 p.m. local time —> events will begin @ 5 p.m. local time.
If any of these actions occur AFTER 2 p.m. local time —> events will begin @ noon local time the following day.
