Driving the news: Grijalva, the Democratic nominee for the seat previously held by her father, former U.S. Rep. Raúl Grijalva, handily defeated Republican Daniel Butierez yesterday.
Why it matters: The special election should lock up the 218th vote for Rep. Thomas Massie's (R-Ky.) discharge petition to force a vote on releasing the files associated with the investigation into the late Jeffrey Epstein.
A tiny group of stubborn House Republicans, along with their Democratic colleagues, is poised to force an embarrassing vote for the Trump White House.
Grijalva plans to sign the discharge petition if elected, a spokesperson told us.
What's next: Grijalva is expected to be sworn in when Congress returns from recess in early October.
That tees up a floor vote on releasing the files in mid-October.
