Twitter community adds a context note to Joe Biden tweet:  President Joe Biden's official Twitter account tweeted, “Inflation is now down 40% since last summer, and it's come down the last nine months in a row. We have more work to do, but we're trending in the right direction, and we're making real progress.”  Twitter added a label to the post that read "Readers added context they thought people might want to know.” The added context read "Prices increased by 5% in March. This is a lower RATE of inflation from last summer, but still high inflation. Saying inflation is "down" can mislead people into thinking absolute prices are lower when they are higher." The context note also included links to an NBC News article to support the note. The label is part of Twitter’s Community Notes system.
