Here are the three main references I found at ICR:
Has the Big Bang been saved?
The Big Bang Theory Collapses
Bumps in the Big Bang
Note that all of these are about ten years old. The main one seems to be the middle one, which appears to claim that there's more structure to the universe than is allowed for in the Big Bang. News to me! He also claims that there were a host of "Big Bang theory is a dud" newspaper and journal in the early 90's, though he does not provide a single reference.
The third entry claims that the COBE anisotropies could be caused by the Sunyaev-Zel'dovich effect, something that is beyond me to address. Meanwhile, he admits that creationists have no explanation for the CMBR.
