The neighbor of Sen. Rand Paul who allegedly assaulted the Kentucky Republican while he was mowing his lawn has now signed a federal plea agreement.

The U.S. Attorney in Indianapolis made the announcement Friday. His office was assigned the case following the recusal by the U.S. Attorney in the western part of Kentucky.

“Assaulting a member of Congress is an offense we take very seriously,” U.S. Attorney Josh Minkler said. “Those who choose to commit such an act will be held accountable.”

Rene Boucher, the 58 year-old neighbor of Paul, apparently “had enough” of the senator placing yard waste near their property line. Boucher tackled Paul, resulting in the senator sustaining a half-dozen broken ribs and related complications including pneumonia.

 The U.S. attorney’s office said no date has been set for the federal court considering the plea.
