The White House says, a new package of economic sanctions on Russia and Iran unacceptably constrains the President's authority. <br/><br/>Democrats complained that the Trump Administration is trying to weaken the penalties. <br/><br/>The legislation sailed through the Senate nearly a month ago in response to Russia's meddling in the 2016 Presidential election and its belligerence toward Ukraine. <br/><br/>But the bill stalled in the House with Democrats and Republicans blaming each other. <br/><br/>Marc Short, White House legislative director, says the administration backs the new sanctions on Russia and Iran. But he appeared to object to a key part that would give Capitol Hill a much stronger hand in determining Russia sanctions policy.<br/><br/>The bill would require a congressional review if President Donald Trump attempts to ease or end penalties against Moscow.
