Republican U.S. Sen. Ron Johnson is supporting President Trump in light of an impeachment inquiry from House Democrats. Johnson says he sees nothing wrong with Trump asking Ukraine and China to investigate former Democratic Vice President Joe Biden and his son. And Johnson says it's "perfectly appropriate" for American law enforcement agencies to enlist the help of other countries.

In this week's Capitol Notes conversation, WUWM's Marti Mikkelson asked JR Ross of WisPolitics.com what he makes of Johnson's steadfast support of the president.
