On Sunday, almost 1.6 million American air passengers passed through security checkpoints. Compare that to just about 130,000 the same day last year.

And, the Biden administration’s plan to go after tax evaders. Guests: Axios' Joann Muller and Felix Salmon. Credits: Axios Today is produced in partnership with Pushkin Industries.
