Amy Pemberton sent a message to Dick Costolo that said:
I call on Twitter to begin IMMEDIATELY complying with it's terms of service by deleting the account @realDonaldTrump and by banning the account's owner, Donald Trump, until such time as he demonstrates that he will comply with your term of service 100%, with an understanding that any violations will result in an immediate and permanent ban. Fact checking is not enough - you need to ban him.
I also call on you to immediately and publicly apologize to the widower of Lori Klausutis, both for refusing to remove the tweet and for claiming that the tweet wasn't a violation of your terms of service. The claim that the lies Donald Trump told about her death on Twitter are not violations of your term of service is in itself a bald-fact lie.
Finally, I call on Twitter to immediately begin enforcing its terms of service for all accounts, regardless of whether or not the owner of the account is wealthy or a high office holder. Its past time for you to take actions to clean up the cesspool Twitter has become.
