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.
Boucher faces possible prison time, and his attorney says he is "very regretful" about the attack and that it had to do with the upkeep of their yards.
Baker said Friday the attack was "completely, 100 percent out of character" for Boucher. The neighbor, Rene Boucher, has admitted to the assault but says it was not politically motivated. Paul has since said he's recovering well from the attack.
"Dr. Boucher is very meticulous about that. Sen".

Boucher could face up to 10 years in prison and a fine of up to $250,000, according to the Assistant U.S. Attorney Bradley P. Shepard.
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.
