In 1946, Ross ran for a seat in Congress from New York's 5th congressional district. Normally, a Democratic district, Ross won election as one of 55 Republicans who swept to victory in the 1946 elections. His time in Congress was short as T. Vincent Quinn ousted him in 1948 and again in 1950. From 1949 until 1952, he was a director of sales and marketing for the Southern Athletic Company, which was owned by his brother-in-law. At the end of 1951, Quinn resigned his seat in Congress to become the Queens County District Attorney and Ross won the February 1952 special election replace him.

Defense Department
After his defeat, Ross became the Washington liaison for the New York Republican State Committee. Later, he worked for Assistant Secretary of Defense for Legislative Affairs, Fred A. Seaton. When Seaton left to work as an assistant to President Dwight Eisenhower in 1955, Ross was appointed to Seaton’s position. Ross’ initial months in the post were tumultuous. Ross, acting on a directive from Secretary of Defense, Charles E. Wilson to ensure that all releases made a “constructive contribution” to national defense. Congressional committees and reporters charged him with censorship when he made significant edits to speeches by staffers, service secretaries and the Joint Chiefs of Staff. A congressional subcommittee found that the Department of Defense’s policies were the most restrictive of any agency. He also incorrectly confirmed a 1956 report that three senators including, John L. McClellan, had requested the Air Force to send a pair of planes to Europe for them. The Defense department ultimately apologized to the senators for the slip-up. In January 1957, Ross took a leave of absence in response to a congressional investigation into possible conflicts of interest involving a clothing business run by his wife and owned by his brother-in-law. The subcommittee, headed by Senator McClellan, looked into an $835,150 contract for Army trousers that was awarded to Wynn Enterprises. The Senators also looked into an allegation that Ross set up a meeting for his brother-in-law with an army officer to ostensibly discuss clothes procured under another defense contract. The committee also looked into information that Ross was still affiliated with the company, despite assurances that he severed all ties. Ross denied all the allegations and an investigation by the Defense Department found no violations of the law and no improper use of influence. Nevertheless, Ross concluded that the charges would affect his ability to serve and resigned in February 1957.
