UPDATE, 3:34 p.m. – Representative Adam Kinzinger (R IL-16) has released the following statement regarding Rep. Schock’s resignation:

“During my time in Congress, I have come to know and respect Aaron Schock’s dedication to serving his constituents, his tireless advocacy for our country’s future, and the people in the 18th District. Aaron was constantly looking for ways to end partisan gridlock, never afraid to reach across the aisle to find real solutions for American families. I was saddened to learn of his resignation and wish him the best.”

PEORIA – U.S. Representative Aaron Schock (R IL-18) announced his official resignation Tuesday in this statement:

“Today, I am announcing my resignation as a Member of the United States House of Representatives effective March 31st.

I do this with a heavy heart. Serving the people of the 18th District is the highest and greatest honor I have had in my life. I thank them for their faith in electing me and letting me represent their interests in Washington. I have given them my all over the last six years. I have traveled to all corners of the District to meet with the people I’ve been fortunate to be able to call my friends and neighbors.

But the constant questions over the last six weeks have proven a great distraction that has made it too difficult for me to serve the people of the 18th District with the high standards that they deserve and which I have set for myself.

I have always sought to do what’s best for my constituents and I thank them for the opportunity to serve.”

Schock as been the target of an ethics probe over his personal use of campaign contributions.
