The Justice Department said Boucher has signed a plea agreement at the federal level, though date has been set for the official taking of his guilty plea and sentencing.

The plea deal also envisions that Boucher will make restitution to Paul, who was seriously injured. Boucher made a "running tackle" of Paul in the lawmaker's yard, it said. "Paul takes a different approach", Baker said.
The document said Paul "did not see the attack coming until the last second, and was unable to brace for the impact".
Paul said he was mowing his yard with a riding mower, but had stepped off the mower to gather sticks. In a later interview with the FBI, Boucher again confessed to tackling Paul, the document said.
