Lyndon B. Johnson Serves as US Representative for the 10th Congressional District of Texas

In 1937 Johnson successfully contested a special election for Texas's 10th congressional district, which covered Austin and the surrounding hill country.

He ran on a New Deal platform and was effectively aided by his wife. He served in the House from April 10, 1937 to January 3, 1949.
President Roosevelt found Johnson to be a welcome ally and conduit for information, particularly with regard to issues concerning internal politics in Texas (Operation Texas) and the machinations of Vice President Garner and Speaker of the House Sam Rayburn. Johnson was immediately appointed to the Naval Affairs Committee. He worked for rural electrification and other improvements for his district. Johnson steered the projects towards contractors that he personally knew, such as the Brown Brothers, Herman and George, who would finance much of Johnson's future career. In 1941, he ran for the U.S. Senate in a special election against the sitting Governor of Texas, radio personality W. Lee "Pappy" O'Daniel in an election marked by massive fraud on the part of both campaigns.Johnson was not expected to win against the popular governor, but he ran a strong race and was declared the winner in unofficial returns — ultimately losing due to controversial official returns.

War record
After America entered the war in December 1941, Johnson, still in Congress, became a commissioned officer in the Naval Reserve, then asked Undersecretary of the Navy James Forrestal for a combat assignment. Instead he was sent to inspect the shipyard facilities in Texas and on the West Coast. In the spring of 1942, President Roosevelt needed his own reports on what conditions were like in the Southwest Pacific. Roosevelt felt information that flowed up the military chain of command needed to be supplemented by a highly trusted political aide. From a suggestion by Forrestal, President Roosevelt assigned Johnson to a three-man survey team of the Southwest Pacific.
Johnson reported to General Douglas MacArthur in Australia. Johnson and two Army officers went to the 22d Bomb Group base, which was assigned the high risk mission of bombing the Japanese airbase at Lae in New Guinea. A colonel took Johnson's original seat on one bomber, and it was shot down with no survivors. Reports vary on what happened to the B-26 Marauder carrying Johnson. Some accounts say it was also attacked by Japanese fighters but survived, while others, including other members of the flight crew, claim it turned back due to generator trouble before reaching the objective and before encountering enemy aircraft and never came under fire, which is supported by official flight records. Other airplanes that continued to the target did come under fire near the target at about the same time that Johnson's plane was recorded as having landed back at the original airbase.
MacArthur awarded Johnson the Silver Star, the military's third-highest medal, although it is notable that no other members of the flight crew were awarded medals, and it is unclear what Johnson could have done in his role purely as an "observer" to deserve the medal, even if his aircraft had seen combat. Johnson's biographer, Robert Caro, stated, "The most you can say about Lyndon Johnson and his Silver Star is that it is surely one of the most undeserved Silver Stars in history, because if you accept everything that he said, he was still in action for no more than 13 minutes and only as an observer. Men who flew many missions, brave men, never got a Silver Star."

Johnson reported back to Roosevelt, to the Navy leaders, and to Congress that conditions were deplorable and unacceptable. He argued the South West Pacific urgently needed a higher priority and a larger share of war supplies. The warplanes sent there, for example, were "far inferior" to Japanese planes, and morale was bad. He told Forrestal that the Pacific Fleet had a "critical" need for 6,800 additional experienced men. Johnson prepared a twelve-point program to upgrade the effort in the region, stressing "greater cooperation and coordination within the various commands and between the different war theaters." Congress responded by making Johnson chairman of a high-powered subcommittee of the Naval Affairs committee. With a mission similar to that of the Truman Committee in the Senate, he probed into the peacetime "business as usual" inefficiencies that permeated the naval war and demanded that admirals shape up and get the job done. However, Johnson went too far when he proposed a bill that would crack down on the draft exemptions of shipyard workers if they were absent from work too often. Organized labor blocked the bill and denounced Johnson. Still, Johnson's mission had a substantial impact because it led to upgrading the South Pacific theater and aided the overall war effort immensely. Johnson's biographer concludes, "The mission was a temporary exposure to danger calculated to satisfy Johnson's personal and political wishes, but it also represented a genuine effort on his part, however misplaced, to improve the lot of America's fighting men."

Resigned as Texas Director of the National Youth Administration to enter the special election for the 10th Congressional District called after the death of Representative James P. Buchanan. Nine other candidates also entered the election. Johnson backed Roosevelt 100% and handily won the election on April 10.

In Congress, Johnson worked hard for rural electrification, public housing, and eliminating government waste. He was appointed to the House Committee on Naval Affairs at the request of President Roosevelt.

Texas District 10 of the United States House of Representatives is a congressional district that serves the northwestern portion of the Greater Houston region stretching to the Austin area of Texas.
