Iowa Senator Joni Ernst is concerned about President Trump's position on Russia.  She told says Trump should "step up" and deal with Russia, a country she says isn't very friendly toward the United States.  Trump's position on things like Russian hacking in the election has caused concern among many members of Congress--including some Republicans like Ernst.  Trump has expressed a willingness to get along with Russian president Vladimir Putin, but Ernst said leadership against Putin is what's needed.
