Meredith Vieira's Husband Says She Wasn't Offended by Matt Lauer in 2006 Video

Meredith Vieira and Matt Lauer loved sharing a good joke and she had no problem when Matt leered at her and asked her to bend more so he could see her cleavage ... so says Meredith's husband.

Richard Cohen -- a noted journalist and author -- tells TMZ he's aware of the 2006 video TMZ posted Wednesday and said it was not inappropriate. Cohen says they had that kind of relationship where such comments were not off limits.

Richard says during Meredith's 10-year run at "Today" she was never aware of any sexual misconduct allegations lodged against Matt. He was emphatic ... Matt never did anything untoward with his wife. Richard goes on to say he and Meredith occasionally had dinner with Matt and he was nothing but a great guy.

As we reported ... Matt and Meredith had another now-cringeworthy moment last year when she confronted Matt about a "huge bag of sex toys" in his office. As you know, he allegedly gave a sex toy to a female staffer as a gift.
