Last week the White House and congressional Democrats and Republicans were involved in intense negotiations over not only the size of the budget for the remainder of the FY2011 budget, and spending cuts within that budget, but also several GOP “riders,” or policy provisions attached to the bill.
One rider – Section 2262 -- de-funds certain White House adviser positions – or “czars.” The president in his signing statement declares that he will not abide by it.

During his presidential campaign, then-Senator Obama was quite critical of the Bush administration’s uses of signing statements telling the Boston Globe in 2007 that the “problem” with the Bush administration “is that it has attached signing statements to legislation in an effort to change the meaning of the legislation, to avoid enforcing certain provisions of the legislation that the President does not like, and to raise implausible or dubious constitutional objections to the legislation.”
Then-Sen. Obama said he would “not use signing statements to nullify or undermine congressional instructions as enacted into law.”
