An army veteran kneeled with a folded American flag as President Donald Trump's motorcade drove past his family business in Indiana on Sept. 27.
Marvin Boatright said he carried out the protest in response to Trump's remarks about NFL players and their right to protest by kneeling during the national anthem, HuffPost reports.
A Reuters photographer noticed Boatright's protest and snapped a picture that subsequently went viral.
"For the commander in chief to call our citizens 'sons of a b***hes' was totally wrong and beneath the dignity of the office that he holds," Boatright told HuffPost.
Boatright served in the U.S. Army during the 1970s.
"As a veteran, and as an African-American, we have already and we continue to serve for God and country," he added. "But you can have a love of God and country and still be against social injustice. You don't have to separate one from the other."
Sept. 27 was not the first time Boatright caught sight of Trump's motorcade. He saw the then-presidential candidate take the same route in spring 2016.
"I wanted to give him a thumbs down," Boatright said of his previous Trump sighting. "But I didn't do anything. I just looked at him out of respect."
This time, Boatright felt he had to do something.
"We love this country," he added. "We love this flag. But we also love life and liberty for all humanity."
Boatright does not accept the argument that the NFL is not the correct venue for protest.
"The issues that affect our nation can be seen and made visible through sports," Boatright added. "We need to get our racial equality act together, especially as it relates to police action and shootings around our nation ... were never about disrespecting our nation or the flag, which we hold so dear."
In a Sept. 28 Fox News interview, Trump continued to criticize the NFL and team owners for not cracking down on the protests.
"I have so many friends that are owners," Trump said, according to ABC News. "They are in a box. I have spoken to a couple of them. They say we are in a situation where we have to do something. I think they're afraid of their players, you want to know the truth. I think it's disgraceful. And they've got to be tough and they've got to be smart."
Trump tweeted on Sept. 26 that the NFL should "set a rule" prohibiting players from taking a knee during the national anthem.
