"Well if he does show up we need to have new sanctions hanging over Putin's head," Graham said commenting on possible meeting of Russian and U.S. presidents in the White House this fall.
Asked what could those sanctions look like, the politician said: "Well you need to get with Rubio and Van Hollen and myself and others and come up with a set of sanctions that would be a hammer over Russia's head if they continue to interfere in the 2018 election."
"Just have sanctions that can fall on Russia like a hammer. Do not meet with this guy from a position of weakness. You need to do two things you need to harden our electoral infrastructure. You need to be the leader of that movement and you need to work with Congress to come up with new sanctions because Putin's not getting the message," Sen. Graham stressed.
According to him, U.S. President Donald Trump has been tougher than Obama but it's not working: "If you were really tough with Putin he would not be doing what he's doing. So being tougher than Obama doesn't get me to where I want to go. I want this man to stay out of our elections and quit disrupting the world. We need new sanctions. Heavy handed sanctions hanging over his head. Then meet with him," he said.
Earlier, U.S. senate minority leader called for more sanctions on Russia after Trump-Putin summit.
