Today, President Obama signed the last piece of legislation that Congresswoman Gabby Giffords authored before her retirement.
The new law is designed to clamp down on ultralight planes that are used to smuggle drugs into the United States.
In a statement, President Obama said, "I’m confident that while this legislation may have been her last act as a Congresswoman, it will not be her last act of public service."
This final bill from Rep. Giffords passed Congress unanimously.
