Senator Elizabeth Warren says it's important for the U. S. to show Poland and other key allies that it has their back.
Warren has spent the last few days in Poland, meeting with U.S. and Polish officials and learning more about Eastern European Army operations.
She also met with an Army unit from Brockton that is stationed in Poland.
She says with Russia engaging in destabilizing and aggressive activity in the region, it's important to show support to neighboring Poland.
