After months of expressing caution on a push for impeachment, House Speaker Nancy Pelosi launched a formal impeachment inquiry into President Trump Tuesday.

U.S. Speaker of the House Nancy Pelosi rallied with Illinois Democrats Wednesday in Springfield.

If you go to the Illinois State Fair every year, there's no way you've missed the butter cow. Today we'll talk to its sculptor about how it's created. And speaking of the state fair, Speaker Nancy Pelosi is showing up there next week, but she's not the first politician to make an appearance. Plus, George Will is a conservative writer who’s been in the national spotlight for decades. He’s also a native of Champaign. We’ll talk with him about Illinois politics and his latest book, The Conservative Sensibility. Also, do you use an app like Slack or Trello in your office? It turns out some families have co-opted office apps to help them organize things in their personal lives too.

President Trump used his first prime-time address from the Oval Office to make the case for his controversial border wall. The president's demand for $5.7 billion in wall funding — and Democrats' opposition — has led to a partial shutdown of the federal government.

Updated at 3:45 p.m. ET The partial shutdown of the federal government that began just after midnight Saturday won't be ending anytime soon. The Senate has adjourned with no business in the chamber anticipated before Thursday afternoon and, maybe not even then, if congressional leaders and President Trump can't reach an agreement over the president's demand for $5 billion in funding for his border wall.
