Performing hajj and tawaaf with impurity on one's ihraam and clothes

Q: In the days of hajj days, 8, 9, 10 Zul Hijjah, if there is impurity/najasat (urine drops and semen) on the ihraam but the body is clean with valid wudhu, and later while performing tawaf e ziyarat there is impurity/najasat (urine drops and semen) on the clothes, but the body is clean with valid wudhu, will the hajj be valid or not?
