The Islamic State group released a video Tuesday that appears to show the beheading of Steven Sotloff. If confirmed, it would be the second such video in two weeks after the killing of journalist James Foley.
Johnson says Tuesday's video highlights the need for the U.S. to intervene in the Middle East to stamp out the terrorist group. Johnson spoke from Plymouth, Minnesota, where he is helping fellow Republican and Senate candidate Mike McFadden campaign against Democratic Sen. Al Franken.
McFadden says the U.S. should continue targeted bombings in Iraq and possibly Syria, but wouldn't support a boots-on-the-ground invasion. Johnson didn't specify the intervention he supports.
