But on Tuesday, a group of veterans started to show their support for the 49ers quarterback.

The first tweet actually came from Wink Westwood, a Black Lives Matter supporter, on August 28th:
It started to pick up steam on Tuesday.
Taking a bit of a risk to speak out, active duty members used the trend to voice their support:

One pointed out how choosing to defend this nation means protecting everyone's rights equally:
And even used Black Lives Matter in their tweets while expressing their support:
Others said they didn't sign up to fight for a song:

One guy even claimed that there is some stolen valor going on with those saying they're veterans for Kaepernick:

Meanwhile, Kaepernick plans to continue to sit down during the National Anthem, a decision that a lot of Americans aren't taking lightly. The San Francisco 49ers' next game, against the San Diego Chargers, will feature an annual Salute to the Military presentation.
