WASHINGTON — Mick Mulvaney, the interim director of the Consumer Financial Protection Bureau, told banking industry executives on Tuesday that they should press lawmakers hard to pursue their agenda, and revealed that, as a congressman, he would meet with lobbyists only if they had contributed to his campaign.

“We had a hierarchy in my office in Congress,” Mr. Mulvaney, a former Republican lawmaker from South Carolina, told 1,300 bankers and lending industry officials at an American Bankers Association conference in Washington. “If you’re a lobbyist who never gave us money, I didn’t talk to you. If you’re a lobbyist who gave us money, I might talk to you.”

At the top of the hierarchy, he added, were his constituents. “If you came from back home and sat in my lobby, I talked to you without exception, regardless of the financial contributions,” said Mr. Mulvaney, who received nearly $63,000 from payday lenders for his congressional campaigns.

Mr. Mulvaney, who also runs the White House budget office, is a longtime critic of the Obama-era consumer bureau, including while serving in Congress. He was tapped by President Trump in November to temporarily run the bureau, in part because of his promise to sharply curtail it.
