Twitter community adds a context note to Joe Biden tweet:  The official Twitter account for the president tweeted, “In six days, a month’s supply of insulin will be capped at $35 for our seniors." Twitter added a label to the post that read "Readers added context they thought people might want to know.” The added context read "Medicare Part D beneficiaries insulin copays will be limited to $35 per month for starting in 2023. ...the Senate Parliamentarian ruled broader insulin reform for non-Medicare patients could not be included in the legislation." The note also included a link to support the assertion. The label is part of Twitter’s Community Notes system. Twitter users are able to sign up as contributors to add context to tweets.
