Robinhood Markets Inc. and Citadel Securities responded to renewed criticism of their actions during January’s meme-stock frenzy, after retail investors filed a class-action lawsuit last week.

Citadel Securities, whose founder Ken Griffin testified about the episode during a February congressional hearing, fired off a series of tweets late Monday denying allegations that it pressured Robinhood to restrict trading. Robinhood, led by Chief Executive Officer Vlad Tenev, said in an emailed statement Tuesday that the lawsuit paints “a false narrative of collusion” with Citadel Securities.
