Fact check: Gas prices when Trump left office were much higher than he now claims

Washington (CNN) Former President Donald Trump has been attacking President Joe Biden over this year's increase in gas prices -- and greatly exaggerating the size of that increase.
In a Fox News interview that aired on Sunday, Trump said , "Look, when I left, gasoline was $1.87.
And now it's at $7.70 in California, in different places in California, and it's heading that way everywhere."
Facts First: Both of Trump's claims about gas prices at the time he left office were off by more than 50 cents per gallon.
The national average for regular gas on his last day in office, January 20, was $2.393 per gallon, not $1.83, $1.86 or $1.87, according to data provided to CNN by the American Automobile Association.
And while there is a : Both of Trump's claims about gas prices at the time he left office were off by more than 50 cents per gallon.
The average gas price in California was $4.704 on Sunday and $4.705 on Tuesday, according to AAA data.
That was the highest average for any state, but it was far from Trump's claims of $7.50 and $7.70.
In the interview that aired on Sunday, Trump said that gas was selling for $1.87 both "when I left" and "a year ago."
In context, the "a year ago" very much seemed to still be referring to prices at the time he left office, which was actually 10 months ago.
But for the record, he would have been incorrect even if he was talking about prices a full year prior to the interview's air date.
The national average gas price was $2.113 per gallon on November 21, 2020, according to AAA.
