U.S. President Donald Trump has the
legal authority to keep U.S. forces in Iraq and Syria indefinitely, Pentagon and State Department officials said in a pair of letters released this week.
The letters detail the Trump administration's plan for an open-ended mission for U.S. forces,
beyond the fight against the Islamic State group. The letters - first reported by
The New York Times - were to Virginia Democrat Sen. Tim Kaine, an advocate for a replacement for the post-9/11 war authorizations for the use of military force.
The letters come amid
various efforts from
congressional Republicans and Democrats to have Congress approve a new authorization, or AUMF.
Kaine and other critics argue the White House's use of authorizations from a decade and half ago is a legal stretch. He called on Trump to seek a new authorization.
"As I have long feared, we are moving from administrations exploiting the blurry authority between the president's and Congress's shared war powers to the alarming belief that Congress doesn't need to be involved at all," Kaine said in a statement, adding that Trump is "acting like a king by unilaterally starting a war."
In the letters to Kaine, not only is the end date of U.S. operations in Iraq and Syria vague - so is the number of U.S. troops working to defeat the remnants of ISIS. The Defense Department publicly says that number is 2,000, but has acknowledged that number omits troops on "sensitive missions."
