Lehigh Valley Congresswoman Susan Wild is a Democrat who backs President Trump's new trade deal with Mexico and Canada. Sen. Pat Toomey is a Republican who does not. "It's a free and fair trade agreement. It's completely reciprocal. There are zero tariffs on manufacured goods. There are zero tariffs on almost all agricultural goods. So you have this free and fair reciprocal agreement, which, by the way, resulted in a 500-percent increase in exports to Mexico. Somehow this was unacceptable to the administration," Toomey says. He says the Trump administration doesn't like the NAFTA deal because there has been a huge trade deficit with Mexico since its inception in 1994. However, Toomey tells NBC's "Meet the Press" the new U.S./Mexico/Canada trade deal diminishes trade and will harm our exporters.

During the pregame events on ESPN, students from both West Point and the Naval Academy were seen making the gesture to the camera.
