Can a state ban federal agents?
<p>Lets say the governor of FL decided to ban all federal agents.</p>
<ol>
<li>Does he have to power to enact something like that?</li>
<li>Can he remove their law enforcement authority in the state?</li>
<li>Can he force them to leave the state?</li>
<li>Can he arrest any agent who decided to violate the governors orders?</li>
<li>Are any Police/Sheriffs arresting the agents breaking the law?</li>
</ol>

<p>1-3: This would be prohibited under Article VI, paragraph 2 of the US Constitution, which provides that federal law, and the ability to enforce that law, has supremacy over state law. <a href="https://www.law.cornell.edu/wex/supremacy_clause" rel="nofollow noreferrer">As summarized by Cornell Law</a>, the Supremacy Clause:</p>
<blockquote>
<p>establishes that the federal constitution, and federal law generally, take precedence over state laws, and even state constitutions. It prohibits states from interfering with the federal government's exercise of its constitutional powers...</p>
</blockquote>
<p>4: Not legally; see above.</p>
<p>5: Yes, probably a lot of laws. Those charges could range anywhere from interfering with a federal investigation, wrongful imprisonment, assault, or kidnapping.</p>
<p>I think it's important to point out that it is highly unlikely the situation would ever escalate to 4, let alone 5. The federal government is incredibly well resourced with regards to being able to move its law enforcement officers throughout the country. And that's not withstanding that the FBI and other agencies (CBP, TSA) are already stationed in any particular state. A non-zero number of those agents are also residents of the state they're stationed in, which would complicate things further.</p>

<p>It is fundamental that Feds trump states.</p>
<p>The DOJ was created in 1870 to <a href="https://www.smithsonianmag.com/history/created-150-years-ago-justice-departments-first-mission-was-protect-black-rights-180975232/" rel="nofollow noreferrer">enforce Federal Laws that protected former slaves when the states would not</a>.</p>
