The White House is trying to improve its icy relationship with the oil-and-gas industry, but things are far from “hunky-dory,” a top energy aide to President Obama said Monday.

“The notion that we rolled out the welcome mat or have this hunky-dory relationship that we’re all holding hands and singing ‘Kumbaya’ is not exactly where we’re at today,” White House energy adviser Heather Zichal said.

Zichal assessed the state of the relationship — and admitted to some regrets — at a natural-gas event Monday hosted by the American Petroleum Institute, the powerful oil industry trade association.

Officials should have worked harder in the early years of the administration to communicate with the industry, Zichal said.
