A Maine lawmaker charged with pulling a gun in a parking lot confrontation is due in court as a legislative leader seeks to ban him from the State House.

Rep. Frederick Ladd Wintle, a Republican from Garland, has been in jail since being charged Saturday with criminal threatening with a dangerous weapon and carrying a concealed weapon. He is due in court Monday afternoon.

The confrontation happened outside a Dunkin' Donuts in Waterville. The victim told police that Wintle accused him of being a drug dealer and mentioned the death of a boy earlier in the week in a homeless shelter.

Lawmakers have expressed concern about Wintle's increasingly erratic behavior. House Speaker Robert Nutting asked that a judge make it a condition of bail that he's banned from the State House complex in Augusta.
