Michael David Smith of Pro Football Talk noted the leaked messages referenced guns and, on the topic of suppressors, Fromm wrote: "Just make them very expensive so only elite white people can get them haha."
The 21-year-old Georgia native spent the past three years as a starter at the University of Georgia. The Bills selected him in the fifth round of the 2020 NFL draft in April.
Fromm's apology comes amid ongoing worldwide protests of police brutality and racial injustice after the killing of George Floyd, a 46-year-old black man, while in Minneapolis Police Department custody last week.
Buffalo head coach Sean McDermott discussed the situation Wednesday, telling reporters of the recent events:
"I'm disappointed. As a coach in the NFL, I know this hits very close to home, or hits directly home for a lot of the guys on our football team. When we talk about doing things the right way, I feel strongly about, as a country, right now we need to unify. I know emotions are very high right now and that's to be expected, but as I shared with our players, let's channel that energy into doing good in our communities."
McDermott also spoke of a picture posted of Bills players during a training session last week as an illustration of what everybody should try to accomplish.
"I think it's a great example, that visual of what our world needs to look like with the guys smiling together, hands on each other's shoulders. I think that's a great snapshot for America," he said.
Fromm signed a four-year, $3.6 million rookie contract with the Bills in May.
