Greta Twombly resigned Friday as chief of staff to Student Association President Vishal Aswani, writing in a letter addressed to Aswani that her position had become “pointless.”

Twombly is is the fifth member of Aswani’s cabinet to resign. In December, when Aswani’s vice president of public affairs resigned, Aswani’s cabinet held a meeting and warned him to “shape up” or expect more resignations. After that meeting, Aswani pledged to open the doors of communication with campus media outlets and improve communication within his cabinet. Twombly said in her resignation letter that little changed.

“A Chief of Staff cannot serve effectively if their boss will not even return their calls, respond to emails, and refuse to meet with them,” Twombly wrote. “By pushing me out and isolating himself amongst a close group who refuse to question him, even when it is necessary, he has become something I can no longer support.”

Twombly, who helped run Aswani’s presidential campaign almost a year ago, said she lost faith in Aswani as a leader.

“I began this year with such hope with such a wonderful team assembled and a leader who I had the utmost faith in. I never thought failure would be an option,” Twombly wrote. “I have no idea what happened between then and now, but I do know one thing that changed, and that is Vishal.”

Aswani did not respond immediately to requests for comment Friday evening.

The full resignation letter:

I first must say that I never thought the day would come. To even type the words hurts greatly and the fact that things have reached this point is entirely disappointing to me.

I began this year with such hope with such a wonderful team assembled and a leader who I had the utmost faith in. I never thought failure would be an option. I have no idea what happened between then and now, but I do know one thing that changed, and that is Vishal. He is not the person whose campaign I ran nearly one year ago. He is not the friend who I sacrificed so much for and who I put a great deal of time and dedication into. I do not know why or how he changed, but he did. He has lost my friendship and my respect.

Our working relationship has deteriorated beyond belief. The manner in which he now operates has effectively made my position pointless. A Chief of Staff cannot serve effectively if their boss will not even return their calls, respond to emails, and refuse to meet with them. By pushing me out and isolating himself amongst a close group who refuse to question him, even when it is necessary, he has become something I can no longer support.

Thus it is with extreme sadness that I must resign my position as Student Association Chief of Staff, effective immediately.

A good leader is one who is open to opinions and healthy criticism. A good leader leans on others for help and support. A good leader is always willing to put others before themselves. Unfortunately, I cannot say that he possesses any of these qualities. It is not true that he never did though. When he approached me more than one year ago to run his campaign, I was thrilled to have the opportunity to really change the way the SA operated and impart a fresh, new attitude. Sadly, he has fallen greater than I ever could have imagined. He is malicious in the way he pits the staff against each other, he lies to further himself, and he pushes out anyone who dares to question even the simplest of ideas. The campaign platform has fallen by the wayside in pursuit for some unidentified greater goal. He has broken countless promises, and he has shattered numerous friendships. Despite all this I still had hope that we could turn things around. Once he completely shut me out and refused to even acknowledge me on the street, I was left with no choice. I do hate having to leave behind such a great group of Vice Presidents, the Senate, and even the Office Assistants, yet I can no longer work for someone who respects me and the organization they lead so little.

I will always look back on my time in the SA with fondness and only regret that it had to end the way it did. I wish the SA the best, as I believe it has a tough few months ahead.

Updated at 8 p.m.:

Charlie Burgoyne, the SA’s vice president of programming, resigned shortly after the GW float rolled down Pennsylvania Avenue. Burgoyne said his resignation was not politically motivated.

“I really left for three reasons,” Burgoyne said. “First, I worked so hard [on the float] and I was maxed out, just exhausted. Second, I’m going to be playing lacrosse this spring for GW, and third I have a research paper with NASA for my research project. But my position really had nothing to do with Vishal and me staying or leaving had nothing to do with him.”
