From the New York Sun:

Senator Brownback yesterday reached a compromise with Senators Lugar and Biden that would pave the way for an American law backing democracy in Iran.
But in a compromise to gain the support of Mr. Lugar, the chairman of the Senate Foreign Relations Committee and Mr. Biden, the committee’s top Democrat, provisions were dropped stating that “there is not a democratic government in
Iran” and supporting an internationally monitored referendum in Iran for
Iranians to change their system of government.
The amendment made yesterday in the Senate to the State Department
authorization bill states that America supports transparent, full democracy in
Iran and the rights of the Iranian people to choose their own system of
government, and includes wording condemning the human rights abuses of Iranians
expressing political dissent inside Iran.
The original version of the bill sponsored by Mr. Brownback, the Iran Democracy
Act, would have funded more pro-freedom broadcasting into Iran.
Under yesterday’s agreement with Mr. Lugar and Mr. Biden, no federal spending
is authorized. But Mr. Brownback says he intends to make another try for the
broadcasting funding soon.
