CEDAR RAPIDS, Iowa (Reuters) - U.S. President Donald Trump, under siege in Washington, defended his record at a raucous political rally in Iowa on Wednesday, rejecting a Russia investigation as a witch hunt and saying he was succeeding against all odds, despite no major legislative achievements.

"All we do is win, win, win,” he told a cheering crowd.
