WASHINGTON – Navy Yard shooter Aaron Alexis may have been taking a prescription drug with a potentially dangerous side effect, according to one lawmaker.

“One of the medications that (Alexis) received does have a side effect that could in fact have been a problem,” Rep. Jeff Miller, R-Fla., chairman of the House Committee on Veterans’ Affairs, tells WTOP. “However, that doesn’t mean that it was, and that’s why we’re asking the VA for a little more information as to what they prescribed, why they prescribed it, how much was prescribed.”

Miller says that doesn’t necessarily mean the medication is to blame. But he would like more disclosures from the VA, which treated Alexis.

“What were the drug interactions? What were the side effects of the drugs that were prescribed by the VA? We do still have some questions that we’re asking,” he says.

The VA has said Alexis was given “medication to help him sleep” and a “medication refill” during two separate visits to VA medical centers in late August.

Miller says he spoke with the Secretary of Veterans Affairs Thursday and also received a briefing along with other members of the House and Senate Veterans Affairs’ committees.

Miller says that while it appears the VA followed proper procedures, he’s also sent a letter telling them to preserve all records and emails concerning Alexis.

“We want to make sure everything that could have been done was done, and that the VA does not do something to change the storyline.”
