Rachel Maddow used simple math to show that Sen. Roger Marshall (R-KS) did not fully repay a Kansas bakery for 2020 campaign cookies as he claimed, while highlighting the aggressive debt-collection tactics he once used against his own patients.

Rachel Maddow calculated that Sen. Roger Marshall (R-KS) paid $1,300 of a $1,357.50 "double" repayment claim to Holly's Sweet Treats in Hutchinson, Kansas, for 2020 campaign cookies, leaving him short $57.50 — or about $112 short if the 18 percent APR he charged his medical patients were applied over six years.
