Twitter community adds a context note to White House tweet:  The official Twitter account for the White House tweeted, “Gas prices are down by nearly a third since the summer – lowering costs for American families." The tweet included an image of a fake receipt dated December 5, 2022 that listed "Average national gas Price $3.40," "Decline since June peak $1.61,"  "Average monthly savings for a two-car family $170.00," and finished with "Total: Real savings for American families." Twitter added a label to the post that read "Readers added context they thought people might want to know.” The added context read "US EIA data shows regular gas now (12/5) at $3.39. eia.gov/petroleum/gasd… Other key dates & costs during the Biden administration: 1/2021 (Inauguration & minimum price): $2.38 2/2022 (Ukraine): $3.53 6/2022 (maximum price): $5.01 (The family savings estimate assumes use of 106 gallons each month.)"
