His first major legislation, in 1971, expanded black lung benefits and extended eligibility requirements for afflicted miners, their widows and children. Yatron sponsored legislation, signed into law in 1975, which set up a committee to review the volume of paper wasted in U.S. federal government and offer recommendations to reduce that waste. After its investigation, the Paperwork Commission made recommendations that resulted in savings of $3.5 billion. As a Greek-American, Yatron found personal hardship during the 1974 Turkish invasion of Cyprus. As one in a few Greek-Americans in the U.S. Congress, he took leadership in implementing U.S. assistance that ultimately led to a cease-fire in the region. In 1973, Yatron traveled to Europe delivering a speech to the European Parliament in France, urging NATO countries to take more initiative in absorbing the costs of defending Europe.
