The first of two debates between Senator Elizabeth Warren and her Republican challenger John Deaton was held last night. 

Deaton attacked Warren on immigration and says she supports an open border, with Warren saying Republicans offer no border plan because it works for them as an election issue. 

The candidates also sparred with each other on issues that include abortion, Israel and education during the televised studio debate. 

Warren is seeking a third term in the Senate, and she will square off against Deaton again tomorrow in Springfield.
