In 1940, when Latvia was occupied by the Soviet Union, it became a subordinate agency of the Telegraph Agency of the Soviet Union (TASS), a status it would keep until Latvia regained independence in 1991.
I 1940, da den sovjetiske okkupation af Letland begyndte, blev LETA underlagt det statslige sovjetiske nyhedsbureau TASS, en status den skulle beholde indtil Letland genvandt sin uafhængighed i 1991.
