In yesterday’s Transportation Committee hearing, John Hall hammered BP American President Lamar McKay about something a number of others have, as well: the amount of money BP has spent on greenwashing of late.

The answer? $10-12 million last year and $20 million this year.

So it’s roughly probably about the same or maybe a little more than the cost of a blowout preventer.

Sounds like Hall would like to prevent businesses from deducting such expenses in the future.
