Exclusive: Michael Boren, a senior official overseeing the US Forest Service, is accused by Democratic senators of ‘inappropriate interference’

Donald Trump’s administration is facing calls to launch an investigation into allegations that Michael Boren, a senior official who oversees the US Forest Service, pressed agency staff to deploy additional resources to fight a fire burning near his Idaho ranch.

Three Democratic senators accused Boren of “inappropriate interference” in a letter seen by the Guardian, demanding answers from Brooke Rollins, the US agriculture secretary. Boren serves as undersecretary of agriculture for natural resources and environment.

Tens of thousands are still under evacuation orders or warnings amid ‘human-caused’, wind-driven blaze

The Hawk fire is about 27% contained, authorities said on Monday afternoon, two days after the fast-moving, wind-driven wildfire sparked near Reno, Nevada.

Authorities added that 23,000 people are under a “go-now” order and 40,000 people are under a “get-set” warning, an improvement from the 90,000 Nevadans under evacuation orders or warnings on Monday morning.

Human-caused Hawk fire covers more than 15,000 acres as blaze approaches University of Nevada campus in Reno

A fast-moving Nevada wildfire exploded to more than 15,000 acres (6,000 hectares) on Sunday, pushing from the Sierra foothills toward the center of Reno and urging nearly 90,000 residents to evacuate as flames threatened neighborhoods and reached the edge of the University of Nevada campus.

The Hawk fire’s “GO NOW” evacuation zone had expanded to the edge of the university campus as strong, gusty winds, low humidity and dry vegetation fueled the blaze, according to Truckee Meadows Fire and Rescue in Reno. Of those urged to evacuate, 42,000 were under strict orders. An additional 45,000 people were in the evacuation warning zone, and encouraged to leave now and be prepared to stay away for several days to clear the roads for first-responders.

Michael Boren requested more aircraft for 7-acre Cabin Creek fire, some of which were diverted from other fires

Michael Boren, the US undersecretary of agriculture for natural resources and environment who oversees the US Forest Service, reportedly pressed agency staff last month to deploy more aircraft to a 7-acre (2.8-hectare) fire that was burning near his Idaho ranch, according to a Washington Post report on Friday.

The Cabin Creek fire in Idaho began on about 12 July as a result of an unattended campfire, and spread across several acres in Idaho’s Sawtooth national forest. By 15 July, the forest service said that the fire was 100% contained.
