Dear SEC Chairman Jay Clayton,

I have been following the controversies surrounding Chinese purchase of the Chicago Stock Exchange. Last night on Fox News, Lou Dobbs said the SEC should not approve it because of national security concerns. I am a Trump supporter and I believe Lou made a valid point.

To get a better understanding of the issues, I wonder why the SEC hasn't posted Congress's letter addressed to the SEC dated September 26, 2017? CHX lawyer James Ongena referenced the letter but the public hasn't seen it. It doesn't sound fair. Could you please post it?

I trust the SEC will arrive at the right decision declining this bad Chicago deal orchestrated by the Chinese government.
