‘Law & Order’: Tony Goldwyn Introduces Baxter’s New Romance With Maggie Siff

We’re going to meet that mysterious Kate, played by Maggie Siff, in DA Baxter’s (Tony Goldwyn) life in the March 13 episode of Law & Order — and of course it’s going to get a bit messy.

In “Crossing Lines,” when an up-and-coming politician is found dead, Shaw (Mehcad Brooks) and Riley (Reid Scott) untangle the victim’s personal life to identify a suspect. Baxter recuses himself to help Price (Hugh Dancy) make the case. Below, Goldwyn explains why and previews the complications it brings to Baxter and Kate’s relationship.
