Hillary Clinton -- Finally, We Can Talk Emails! And Generation Gaps

Nothing like a second chance -- Hillary Clinton ran into our intrepid D.C. photog on Wednesday ... giving him a shot at redemption on that whole email mess.

If you missed it ... Colin shot Hillary on Tuesday, and chose to tackle a topic other than her private emails.

Lo and behold, he ran into her again at Reagan National, and this time he got right to it -- firing off the question everyone wants her to address. Well ... he got closer anyway.
