Congressional Democrats are complaining about the costs to taxpayers of Vice President Mike Pence's decision to fly to an Indianapolis Colts game, and then walk out of the game to protest the decision of some players to kneel at the game.

Pence flew from Las Vegas to Indianapolis, then left the game shortly after arriving after members of the San Francisco 49ers didn't stand for the national anthem. He then flew to Los Angeles.

That had some Democrats, like Adam Schiff, D-Calif., wondering about the costs.

"After all the scandals involving unnecessarily expensive travel by cabinet secretaries, how much taxpayer money was wasted on this stunt?" Schiff asked on Twitter Sunday.

"This was orchestrated to make a point? Sen. Brian Schatz, D-Hawaii, asked on Twitter. "That's not an inexpensive thing to do.'

A CNN reporter tweeted that Air Force 2 costs about $43,000 an hour to fly, which would put the cost of the flight alone at about $200,000, but that excludes the costs of Secret Service protection.

But CNN also reported that some of those costs will be returned, since Pence was traveling to a political event in Los Angeles.
