Rep. Bob Watson was voted out as state House Minority Leader by a vote of the Republican House caucus, WPRO reported Tuesday afternoon.

Watson was convicted on driving under the influence in 2000 in New Hampshire, WPRI reported Tuesday evening.

Watson, a Republican respresenting East Greenwich, R.I., was arrested in Connecticut April 22 and charged with possession of marijuana as well as driving under the influence and possession of drug paraphernalia after he was stopped at a sobriety checkpoint by East Haven police.

Watson acknowledged in a speech in the General Assembly last week that he could have participated in the medical marijuana program, but that he had chosen not to. He said he had not smoked marijuana on the day of the arrest, but that he had smoked it on occasion to deal with pain from pancreatitis attacks he’d suffered starting last November.

After a meeting with the East Greenwich Town Council Monday night, Watson declined to say he would refrain from using illegal drugs in the future.

After the meeting, according to WPRO, the GOP caucus announced that current minority whip, Brian Newberry of North Smithfield, would replace Watson as House minority leader.
