Can the president really order the military to occupy US cities and states?

After a week of both peaceful protests and violent chaos in the wake of George Floyd’s death, President Donald Trump announced, “If a city or state refuses to take the actions that are necessary to defend the life and property of their residents, then I will deploy the United States military and quickly solve the problem for them.”
Is Trump’s warning just bluster? Does the president have the authority to send the military into American cities?
The answer to this question involves a web of legal provisions that help define the president’s constitutional roles as commander in chief and chief executive of the country and that simultaneously try to balance presidential power with the power of state leaders.
‘Protect states in times of violence’
Tracing back to the Magna Carta, the British charter of liberty signed in 1215, there is a longstanding tradition against military involvement in civilian affairs.
However, the U.S. Constitution guarantees that the national government will protect the states in times of violence and permits Congress to enact laws that enable the military to aid in carrying out the law.
Almost immediately after the Constitution’s enactment in 1787, Congress passed a law that allowed the president to use the military to respond to a series of citizen rebellions.
Troops serving as what’s called “posse comitatus,” which translates roughly to “attendants with the capacity to act,” could be called to suppress insurrections and help carry out federal laws.
Following the Civil War, the national government used troops in this capacity to aid in Reconstruction efforts, particularly in states that had been part of the Confederacy.
The use of troops in this manner may even have influenced the outcome of the 1876 presidential election of Republican Rutherford B. Hayes. That happened when, in return for agreeing to withdraw federal troops from the South, Democrats informally agreed to the election of Hayes when the disputed election was thrown to a congressional commission.
Two years later, Hayes signed into law the Posse Comitatus Act, which prohibited the use of the military in civilian matters.
The Posse Comitatus Act has not changed much since that time. The law prohibits the use of the military in civilian matters but, over time, Congress has passed at least 26 exemptions to the act that allow the president to send troops into states.
The exemptions range from providing military personnel to protect national parks to helping states in carrying out state quarantine and health laws......
