Eric Swalwell's campaign in freefall

The scandal surrounding the Bay Area congressman has intensified with new claims involving the misuse of campaign funds and potential immigration law violations.

Allegations that Swalwell sexually assaulted a former staffer have been followed by reports of inappropriate behavior with other women.

As the House returns from recess, pressure is mounting for an expulsion vote, which could also affect other members facing misconduct charges.

Swalwell has denied the allegations, but the political fallout has already upended the race for California's highest office.
