Health and Human Services Secretary Tom Price said Thursday that he believes President Trump still has confidence in him — a day after Trump admitted he was “not happy” with his cabinet member’s use of private planes for personal and government business.

“I think we’ve still got the confidence of the president,” Price said after an event at the National Press Club in Washington, DC, to reporters’ shouted questions. “We’re going to work through this.​”

​Trump on Wednesday said “we’ll see” when asked if he would fire Price.

​”I was looking into it and I will look into it. I will tell you personally, I’m not happy about it,” ​the president told reporters as left the White House for a trip to Indiana about Price’s travel on private planes. “I am not happy about it I’m going to look at it. I let him know it.”​

House investigators are examining Price’s and other Trump administration officials’ use of charter flights after Politico revealed that the HHS secretary spent more than $400,000 on private planes since May and left taxpayers to foot the bill.

Price said he would end the practice until the HHS inspector general finished his review of the trips.

The House Oversight Committee sent letters to Price, 23 others agencies and the White House asking for an accounting of all senior administration travel since the inauguration and reminding them that Federal Travel Regulations forbid the use of private planes for personal use.

​Treasury Secretary Steven Mnuchin ​and Environmental Protection Agency Secretary Scott Pruitt are also being looked at for their use of private planes, according to reports.
