Massachusetts Gov. Charlie Baker said there is "no direct connection" between the Orlando shooter and the Tsarnaev brothers at a press conference Monday morning at the State House.
"At this time, there's no reason to believe there's much to that," he said.
Baker said from what he's been told, federal officials spoke with shooter Omar Mateen years ago after he referenced the Tsarnaev brothers, but did not believe there was cause for concern.
The governor said security at Logan Airport and along the public transit system has been heightened in the wake of the Orlando shooting, and that will continue.
"Our hearts go out to every family and the friends affected by the horrible tragedy and act of terror that took place in Orlando," he said.
On Republican presidential candidate Donald Trump's remarks about Orlando, Baker said he thinks it is "inappropriate and just a mistake" to cast aspersions before all of the information about the shooter and his motives have come out.
He also reiterated his earlier statements that Trump isn't fit to be president.
