BOISE - Boise Republicans were expected to weigh in at a meeting on the political future of Rep. Mark Patterson amid calls for his resignation after the disclosure of his guilty plea in a 1974 sexual assault case in Florida.

Patterson, a first-term GOP lawmaker from Boise, has been invited to appear Tuesday at the Legislative District 15 precinct committee meeting. Some Republican officials including Sen. Fred Martin of Boise said they will seek his resignation.

It was not clear if Patterson planned to attend the meeting.

Martin has arranged extra security for the meeting to be held at a Boise retirement home. Some members of the 15-person GOP committee said they're worried about their safety as they discuss the emotionally charged issue.

Patterson's problems began in November with the revelation that he had lost his concealed weapons permit. Ada County Sheriff Gary Raney revoked it in late October, saying Patterson lied in 2007 on his application by not revealing that he had pleaded guilty 39 years ago to assault with intent to commit rape.

Patterson was 21 in 1974 when he was charged with rape in Tampa. A 46-year-old woman told police that Patterson forced her to have sex twice and threatened to have his Doberman pinscher attack her if she refused, according to police reports.

Patterson served time in jail before agreeing that July to plead guilty to the lesser charge of assault with intent to commit rape and received a withheld judgment and five years' probation.

In Florida, a withheld judgment is generally a legal compromise allowing a person who successfully completes probation to have a judgment of guilt withheld from his or her case.

However, Raney contends it was grounds to bar Patterson from getting a concealed weapons permit.

Patterson was ordered to leave Florida. Two years later, he was released from probation, records show.

Now, Patterson claims the woman lied, and said he only pleaded guilty because he was frightened and was told by his lawyer that the crime would be expunged from his record.

Patterson also contends Raney revoked his concealed weapons permit in retaliation for, among other things, legislation that Patterson sponsored during the 2013 session that would have punished Idaho law enforcement agents for helping the federal government confiscate newly banned weapons.

Patterson said Raney inappropriately released information about his concealed weapons permit that should have remained confidential.

Raney, meanwhile, insists he followed Idaho law and released only information that was public record.

Patterson has told The Associated Press that he's not sure if he'll resign or participate in the 2014 Legislature beginning in January.

He did say that he wouldn't run for re-election in 2014.

As long as Patterson remains in office, he can carry a concealed weapon, based on an exemption granted to Idaho elected officials.
