On Monday's show: Today is Presidents' Day. Who were the best presidents in our nation's history? Who were the worst? We talk with University of Houston professor Brandon Rottinghaus about the Presidential Greatness Project and its latest survey and ranking of those who've held our nation's highest office.

Also this hour: We learn how a group of Black soldiers known as "the Blue Helmets" made history in World War II and moved forward the cause of African Americans in the military. An exhibit about them is on display now at the Buffalo Soldiers National Museum through June 30.

Then, veterinarian Dr. Lori Teller answers pet care questions.

And we get an update on Houston sports from Jeff Balke.
