Tachanun at Shacharis on the day of wedding

In Minhag Ashkenaz is tachanun said in shul at Shacharis if there is a Chassan present who will be getting married later that day?
Is it skipped at Mincha if said at shul much earlier than the wedding or is it only skipped at Mincha if Mincha is davened at the location of the Chuppah immediately prior to the wedding?
