Elizabeth Banks, Bradley Cooper, Will Ferrell, Jon Hamm, Michael Keaton, Rashida Jones and Paul Rudd are just seven of the nearly 100 high-profile figures to sign a letter of support addressed to President Obama, publicizing their endorsement for his Monday decision to take executive action against gun violence.

The effort is sponsored by the Brady Campaign to Prevent Gun Violence. Organizers are urging supporters to support #enough on social media and to ask celebrities at the Golden Globes for their thoughts on gun violence.

The letter begins by thanking Obama for his courageous actions against gun violence, recalling recent mass shooting incidents and reciting gun violence statistics.

“Like you, and like most Americans, we have had ENOUGH,” the letter declares. “We have had enough of seeing unthinkable tragedies happen and nothing being done. This level of depravity should rattle anyone with a conscience.”

It continues by again praising Obama for his recent efforts and calling on the members of Congress “who failed to act on the gun violence epidemic” to take similar action.

“Thank you for beginning to end this national disgrace and show your fellow citizens and the rest of the world that the United States of America does indeed stand for the principles on which it was founded,” the letter concludes.

Additional celeb signees include Mark Ruffalo, Kristen Wiig, Sophia Bush, Nick Cannon, Liam Neeson, Tobey Maguire, Sarah Jessica Parker, Julianne Moore, Tom McCarthy and Olivia Wilde.
