I was disappointed to read your signing statement on HR 2346, the Supplemental
Appropriations Act 2009
("http://www.whitehouse.gov/the_press_office/Statement-from-the-President-upon-signing-HR-2346/").
Your signing statement asserts that this bill's attempt to make foreign
workers' rights figure into World Bank policies would "would interfere
with [your] constitutional authority to conduct foreign relations."

Whilst it is true that the bill would limit your policy options, it is not
true that such policy authority is given to you by the Constitution.  In
fact, Article I, Section 8 of the Constitution states specifically that
"The Congress shall have Power... To regulate Commerce with foreign Nations..."
-- note "Congress," not "President."  The American government is one of
separated, balanced and limited powers.  Unless a law enacted by Congress is
unconstitutional, you cannot unilaterally and capriciously choose to ignore
it.  The specifics of the issue at hand in HR 2346 are less important than
the precedent that your continued use of broad signing statements is helping
to institutionalise.

I had hoped that the practice of negating Congress's intent via signing
statements would end with the end of the Bush government.  When six months ago
you swore to preserve, protect and defend the Constitution, I hoped that you
meant it.
