Ed Royce, debate how the U.S. should respond to Russia's actions as well as the latest terrorism threat. Plus, we go one-on-one with Donald Trump on his weekend visit to Iowa. Roundtable: Rep. Joaquín Castro (D-Texas), Rep. Louie Gohmert (R-Texas), George Will and Donna Brazile. Plus, a special media panel takes on the WashPost sale: George Will, HuffPost's Arianna Huffington, Bloomberg TV's Cory Johnson and The New Yorker's David Remnick.

Trump, as well as former Sen. Rick Santorum (R-Pa.), will address the Family Leadership Summit on Saturday. Santorum recently said he's "open" to running for president in 2016.

For his part, Trump is still pretending to run.
