Senator Bernie Sanders has suspended his campaign to become US president.
Axar.az reports citing foreign media.
The development clears the way for former vice-president Joe Biden to become the Democratic party's nominee.
Mr Sanders, 78, told his campaign staff about his decision on a conference call on Wednesday before addressing his supporters online.
A self-described Democratic socialist, Mr Sanders found early success making healthcare and working-class issues a key part of his election platform.
"We have transformed American consciousness as to what kind of nation we can become and have taken this country a major step forward in the never-ending struggle for economic justice, social justice, racial justice and environmental justice," Mr Sanders told supporters in a live stream.
