ABC News

As conservatives gather in Washington for the annual CPAC convention, ABC News' Jonathan Karl goes one-on-one with two 2016 GOP frontrunners leading different factions of the Republican Party - Sen. Ted Cruz, R-Texas, and Sen. Rand Paul, R-Ky. - and "This Week" is the only place where you'll see them both this Sunday.

Plus, as tensions escalate in Ukraine, ABC News' Martha Raddatz speaks with House Intelligence Committee Chair Rep. Mike Rogers, R-Mich., only on "This Week" Sunday.

And the powerhouse roundtable debates all the week's politics, with Rep. Joaquin Castro, D-Texas, Republican strategist and ABC News contributor Ana Navarro, Wall Street Journal columnist Peggy Noonan, and former Obama White House senior adviser and ABC News contributor David Plouffe.

Plus, in our Sunday Spotlight, ABC News' Dan Harris tells the remarkable story of Misty Copeland, the first African-American soloist in two decades at the prestigious American Ballet Theatre.

See the whole political picture, Sunday on "This Week."
