Reuters - U.S. President Donald Trump on Wednesday warned the Senate against adopting a resolution that would curb his ability to wage war against Iran, saying it would send �a very bad signal� and allow Tehran to act with impunity.

�It is very important for our Country�s SECURITY that the United States Senate not vote for the Iran War Powers Resolution. We are doing very well with Iran and this is not the time to show weakness,� Trump, a Republican, tweeted.

Democrats last month said they had the votes in the Republican-controlled chamber to approve the measure, which would require the president to seek congressional authorization for military action against Iran.
