First, John McCain tried to take credit for Webb's GI Bill after vigorously opposing it. Then George Bush followed suit.
Now Mike Turner (R-OH), who voted against the bill, is also claiming support and credit for its passage. Think Progress documents his statements:
It is our responsibility to provide [veterans] with more than just recognition for their service: we must also make certain that they have the skills they need to accomplish their next mission once they return to civilian life. That is why I was proud to support recently passed legislation that expanded the Montgomery GI bill to provide more funding for veterans to receive a college education. [...]
With the huge impact the GI bill has had on America and the debt that we all owe our nation’s veterans in mind, I was proud to support recent legislation that dramatically expanded the scope and scale of the educational benefits available to our veterans. [...]
I am proud to have supported legislation that will directly provide this benefit for military families and look forward to further working on their behalf in the future.
Webb's GI Bill may well turn out to be the most popular piece of legislation not supported by conservatives ever.
