Hippocampal role in working memory?

    A few weeks ago there was a spot on 20/20 which discussed the
effects of aging on working memory.  The experts they interviewed were
claiming that a progressive degeneration of the hippocampus was
responsible for declines in working memory.
    I've always understood that the hippocampus was only involved in
consolidation - or transfer into long term memory.  My undergrad
neuroscience textbook also states that the ubiquitous ex-hippocampal
patient H.M.'s short-term memory was "intact."  H.M. suffered from
anterograde amnesia, specifically in declarative memory.
    What are your thoughts on this matter?
