Can I say "I told you he is going to the book club" when he has already gone there by now; or is it necessary to back-shift it to past i.e. "I told you he was going to the book club".
So will I be understood perfectly if I used the "is going" version (not back=shifting it). This situation seems new to me. So I thought I'd ask that: Does it seem difficult to understand for the other person if we do not back-shift to past??. And is it gramaticaly correct??
