South Carolina Sen. Jim DeMint sent Obama a letter asking why, as chairman of a Senate Foreign Relations subcommittee, the candidate hasn't held any hearings on Afghanistan. It was an attack used by Hillary Clinton in the Democratic primary.
However, there's an easy response: Senate Foreign Relations Committee Joe Biden has said he wants all hearings on Afghanistan to be held at the full committee level. In case he's forgotten that, Biden reminds DeMint in a letter of his own:
As you are aware, under my chairmanship the Foreign Relations Committee has addressed most Afghanistan issues at the full committee level. I believe that this is the best way of ensuring the most comprehensive examination of the complex issues involved, and of ensuring the highest-level Administration participation.
...Sen. Obama has displayed great leadership on this issue: he called nearly a year ago for the deployment of at least two additional combat brigades to Afghanistan -- it has since become the accepted position of a wide range of U.S. military officials, including the Chairman of the Joint Chiefs of Staff. I look forward to working closely with him, and with you, on any future Afghanistan hearings that might be held in our committee."
In a speech Wednesday, Biden praised Obama's spine and criticized McCain's knowledge of history.
