Voters in the United States are heading to polls to vote in nationwide elections that are being seen as a referendum on Donald Trump's presidency, the BBC reports.
Polling stations opened on the East Coast amid a battle by both Republicans and Democrats to take control of the two houses of Congress.
Polls opened first in the East Coast states of Maine, New Hampshire, New Jersey, New York and Virginia.
Americans are voting for all 435 seats in the House of Representatives and 35 of 100 seats in the Senate - the two bodies that make up Congress. Governors are also being chosen in 36 out of 50 states.
The mid-term elections come half way through Mr. Trump's four years in office.
Mr. Trump attended three rallies on the final day of campaigning, telling his supporters: "Everything we have achieved is at stake tomorrow."
The first polls close at 18:00 EST (23:00 GMT) in Kentucky, and the state could provide some early indications of the expected results.
