September 11 and the Laws That Followed
Terrorist attacks on September 11, 2001, killed nearly 3,000 people. Three days later Congress authorized the President to use force against those responsible. Six weeks after that, it passed the USA PATRIOT Act, expanding government surveillance and investigative powers.
Resulting law: Authorization for Use of Military Force (Pub. L. 107-40); USA PATRIOT Act (Pub. L. 107-56)

Party labels are those used at the time of the vote. The parties' coalitions and positions have changed over time, so a party name in 1864 or 1919 does not map directly onto the party today.
