“Whenever we can, we follow the law,” IRS Commissioner John Koskinen told the House Ways and Means subcommittee on health on Wednesday.

Rep. Kevin Brady (R-Texas), who leads the subcommittee, immediately expressed his concern with the remarks.

“I encourage you to follow the law in all instances,” Brady said.

Koskinen, who was confirmed as head of IRS last December, has repeatedly faced lawmakers’ ire over the agency’s targeting of conservative groups.
