President Trump is renewing a post-9/11 emergency proclamation that gives him broad powers to mobilize the military, hire and fire military officials, and work around limits on the number of generals that can serve.

For the second time during his presidency, Trump announced Monday his administration is renewing the post-9/11 emergency proclamation. Trump is the third president to renew the proclamation.

"Because the terrorist threat continues, the national emergency declared on September 14, 2001, and the powers and authorities adopted to deal with that emergency must continue in effect beyond September 14, 2018," Trump said in a notice to be sent to Congress.

The proclamation grants the president, in addition to the aforementioned powers, the ability to the ability to call up the national guard and deploy troops overseas.

Former President George W. Bush signed Proclamation 7643 in 2001, days after terrorists crashed planes into the World Trade Center, the Pentagon, and a field in Pennsylvania.

The National Emergencies Act requires that the president renew the emergency at the end of each year or at the date the proclamation lapses. Congress is also supposed to review the state of the emergencies ever six moths, but it, notably, never has.
