During the 1906 gubernatorial campaign, Hill frequently spoke against the Democratic nominee John B.

In the 1912 United States presidential election, Hill backed Theodore Roosevelt over William Howard Taft.^[15] He joined the Progressive Party and spoke frequently for its 1913 gubernatorial candidate, Charles Sumner Bird. Hill returned to the Republican party in 1915 to stump for gubernatorial nominee Samuel W. McCall.^[16] In 1917, Hill was a candidate for at-large delegate to the Massachusetts Constitutional convention, but lost to Charles F. Choate Jr. after a recount.^[17]

During World War I, Hill served as a judge advocate general in the United States Army. He was commissioned as a major in December 1917 and served in France from January 1918 to June 1919, during which time he handled property damage claims made by French citizens against the U.S. Army.^[1] He mustered out with the rank of Lieutenant Colonel.^[2] From 1919 to 1922, Hill was corporation counsel for the City of Boston.^[18][1]

On June 1, 1923, Hill returned to the district attorney's office, this time as an assistant to Thomas C. O'Brien.^[3] He was assigned a number of notable cases, including the blackmail case against William J. Corcoran and the banking law violation case against John H. H. McNamee of the Prudential Trust Company.^[19] Hill never intended to be a permanent member of O'Brien's staff and left in 1924.^[20]

In 1923, Hill served as counsel for Sacco and Vanzetti during their petitions for a new trial.^[21][1] He successfully got Sacco declared insane and committed to Bridgewater State Hospital.^[22]
