He’s written letters to TD Bank and Bank of America asking them to revoke credit lines to gun manufacturers. From the Leader Post:

TD Bank suddenly found itself in the crosshairs of the high-calibre political debate over gun control after Chicago Mayor Rahm Emanuel sent a letter to the bank’s U.S. subsidiary asking it to stop lending money to gun manufacturer Smith & Wesson because the company doesn’t support gun controls.

More at the link including excerpts from the letters. This is only important because of a story I reported a few weeks ago about Democrat mayors threatening to boycott gun makers who don’t agree with Obama’s gun control push. Is Emanuel now planning to threaten banks that do business with gun makers, too?
