I don't know when Trump will use it, but I think it'll be soon.
Remember that the Act has been invoked numerous times in the past -- and Trump certainly has good reason to invoke it now. I don't believe doing so will be as toxic as some think it will. Of course, the Commies and paid protesters will make a big deal about it, but most of them will be in custody (or dead, or back home and out of the riot business) before long after the Act is invoked.

The Insurrection Act of 1807 has been invoked about 30 times in U.S. history by 15 Presidents, and once illegally by an Army general. It allows the President to deploy federal military forces or federalize the National Guard to suppress insurrections, enforce federal laws, or protect civil rights.
Thomas Jefferson first invoked the Act in 1808 to enforce the Embargo Act around Lake Champlain. Andrew Jackson used it multiple times in the 1830s, including to respond to Nat Turner’s Rebellion in 1831.
Abraham Lincoln invoked it in 1861 at the start of the Civil War to suppress Southern secession. Ulysses S. Grant used it over ten times in the 1870s, primarily to combat Ku Klux Klan violence and enforce Reconstruction-era civil rights across the South.
Rutherford B. Hayes invoked it during the 1877 Railroad Strike and the Lincoln County War in New Mexico. Grover Cleveland used it to suppress the Pullman Strike in 1894 and to protect Chinese immigrants during riots in the 1880s.
In the 20th century, Dwight D. Eisenhower invoked it in 1957 to enforce school desegregation in Little Rock, Arkansas, federalizing the National Guard to protect Black students.
John F. Kennedy used it in 1962 and 1963 to enforce desegregation at the University of Mississippi and the University of Alabama, overcoming resistance from Governor George Wallace.
Lyndon B. Johnson invoked it multiple times during the civil rights era, including to protect marchers in Selma, Alabama (1965) and to quell riots in Detroit (1967) and other cities following the assassination of Martin Luther King Jr. in 1968.
Ronald Reagan invoked it in 1987 to end a prison riot in Atlanta involving Cuban detainees. George H. W. Bush invoked it in 1989 after Hurricane Hugo in the U.S. Virgin Islands and most recently in 1992 to quell the Los Angeles riots after the Rodney King verdict.
The Act has not been invoked since 1992, and its use has generally been reserved for situations where state authorities are overwhelmed or actively obstructing federal law or constitutional rights.
Yes, I agree it should be invoked soon in 2026.
