Retired Gen. Charles Q. Brown Jr. is speaking out against Donald Trump‘s administration for using the military to target American cities. Brown expressed his thoughts in an essay written for Foreign Affairs.

What did Charles Q. Brown Jr. say in his criticism of the Trump administration?

While he did not specifically mention any government officials in his essay, Brown made it clear that he is disappointed with the Trump administration for targeting blue states.

“In the face of a genuine national disaster, the public will readily embrace the military’s help,” Brown wrote. “But when presidents use the armed forces for more politically contentious missions, such as addressing domestic crime in cities, the work of the military becomes more fraught.”

While the government claimed to be fighting back against crime, Brown and many other critics said the administration is exceeding its authority with the use of the military.

“Resorting to a military solution rather than fixing the underlying incapacity or dysfunction in civilian institutions diverts the military from focusing on its primary combat mission,” Brown wrote. “And as [George] Washington knew, it is not the military’s job to save the republic from political impasses. Indeed, if you ask too much of the military, you risk the entire enterprise.”

Shortly before he published the latest essay, Brown also issued a statement to speak out against Trump for removing top generals.

“What is starting to happen now, it is not about merit. All of these people who are being removed are very well-experienced,” Brown said, per The Wall Street Journal.

Who is Gen. Charles Q. Brown Jr.?

Brown made history when Trump nominated him as Air Force chief of staff in 2020, The Daily Beast reported. The president said at that time that Brown is the “first-ever African-American military service chief.” He also described Brown as “a Patriot and Great Leader.” However, Brown’s relationship with Trump eventually fell apart, according to The Daily Beast.

President Joe Biden later nominated Brown as chairman of the Joint Chiefs of Staff, but he was fired when Trump returned for a second term as the administration launched its anti-DEI campaign.
