Q: Which one is the second highest civilian award in the USA?  

The Presidential Citizens Medal is an award bestowed by the President of the United States. It is the second-highest civilian award in the United States, second only to the Presidential Medal of Freedom. Established by executive order on November 13, 1969, by President Richard Nixon, it recognizes an individual "who has performed exemplary deeds or services for his or her country or fellow citizens." Only United States citizens are eligible for the medal, which may be awarded posthumously.

The medal is a disc of gilt and enamel, based on the Seal of the President of the United States, with the eagle surrounded by a wreath of leaves. The medal is suspended on a ribbon, dark blue with a light blue central stripe and white edge stripes.
