Former U.S. Attorney Matt Mead (R) was sworn in on Monday as Wyoming’s 32nd governor.

Mead served as the state’s U.S. Attorney from from 2001 to 2007. He already has named several of his former colleagues from the office to his administration.

At the swearing-in ceremony and at the inaugural ball that night were several former U.S. Attorneys, according to former Colorado U.S. Attorney Troy Eid, who attend the events.

Among those in attendance were Bill Mercer of Montana, Johnny Sutton of the Western District of Texas, John Ratcliffe of the Eastern District of Texas, Tom Moss of Idaho and Susan Brooks of the Southern District of Indiana, according to Eid.

Senate has now confirmed 55 of Obama’s U.S. Attorney nominees.

The chamber has yet to consider another 15 U.S. Attorney nominees who are waiting for votes in the Senate Judiciary Committee. The Senate also has yet to vote on two U.S. Attorney nominees who were approved by the panel Thursday.

Branches of the Idaho U.S. Attorney’s office received in the mail Monday a suspicious white powder commonly associated with chalk, The Spokesman-Review reported Tuesday.

The nontoxic substance  of calcium carbonate was sent to the branches in Boise and Coeur d’Alene, in addition to other federal offices in Idaho, Washington and Utah. Thomas E. Moss has led the Idaho U.S. Attorney’s Office since 2001.

Threatening letters accompanied the powder. But FBI special agent Frank Harrill declined to elaborate, telling the newspaper that the investigation is “very active.”

KREM 2 News in Spokane, Wash., reported that many of the envelopes were postmarked from the city. A bomb was found in March outside the Thomas S. Foley U.S. Courthouse in Spokane.

Harrill told The Spokesman-Review that there is no indication of a connection between Monday’s letters and the bomb incident, which is still under investigation.

President Barack Obama unveiled two nominees for U.S. Attorneys for Idaho and Maine, the White House announced Wednesday.

They are:

- Thomas Edward Delahanty (Maine): The Maine Superior Court Justice has held his current position since 1983. From 1990 to 1995 he served as the court’s Chief Justice. Before becoming a judge Delahanty from 1981 to1983 was a partner at Delahanty & Longley. He was the state’s U.S. attorney from 1980 to 1981.

Olson worked at Justice Department headquarters in the civil rights division as a trial attorney from 1992 to 1996 and deputy director of operations and assistant to the director on the National Church Arson Task Force from 1996 to 1997.

Obama has now made 54 U.S. Attorney nominations. The Senate has confirmed 34 U.S. Attorneys thus far.

Two Assistant U.S. Attorneys in Idaho are said to finalists for the state’s top federal prosecuting job, a person familiar with the situation told Main Justice recently. But Idaho’s only congressional Democrat, Rep. Walt Minnick (D-Idaho), told us he submitted only one name to the White House for U.S. Attorney.

Minnick spokesperson John Foster declined to comment. Idaho Assistant U.S. Attorneys Deborah Ferguson and Wendy Olson have been mentioned in Idaho as likely candidates, the person with knowledge of the selection process said.

Ferguson works on environmental cases in the office’s civil division. Olson is the senior litigation counsel in the criminal division. She was honored last month in Washington at Attorney General Awards Ceremony for her work on a triple homicide in Coeur d’Alene, Idaho. Read a list of the honorees here.
