President Donald Trump's racist tweets attacking four House Democrats sparked a fight that has dominated Washington for days and spilled onto the 2020 campaign trail. Trump has said that he's "winning" the political debate over his actions, while Democrats maintain that the comments were further proof of Trump's animosity toward minorities and immigrants.

The debate will likely take a back seat next week when former special counsel Robert Mueller testifies before Congress. The high-profile hearings will put Mueller's Russia investigation back in the spotlight, and give lawmakers from both parties a chance to question Mueller in public for the first time since he stepped down from his appointment.

It was a busy week in politics. Syndicated columnist Mark Shields and David Brooks of the New York Times are on hand to break it all down.
