Former US Vice President Mike Pence has withdrawn from the 2024 presidential race, saying "this is not my time".
He made the announcement at the Republican Jewish Coalition in Las Vegas on Saturday afternoon.
"We always knew this would be an uphill battle, but I have no regrets," he wrote in a statement.
Mr Pence is the first major Republican candidate to suspend his campaign in a race led by former President Donald Trump.
Mr Pence had languished in recent polls and had struggled to gain the support of Republican voters.
The former vice president's campaign had also racked up large amounts of debt, with Mr Pence ending September owing $621,000 (£512,038) and having only US$1.2m (£989,446) in the bank - significantly less than other Republican rivals.
"I am leaving this campaign, but I will never leave the fight for conservative values," he wrote in a statement addressed to his supporters.
The 64-year-old lost the support of many Republican voters when he publicly broke with Mr Trump over the 6 January Capitol riot in 2021, and when he presided over the certification of Joe Biden's 2020 election results in Congress.
Mr Trump admonished Mr Pence for lacking "courage" when he refused to overturn the Democratic leader's election victory.
Some rioters were heard chanting "hang Mike Pence" as they stormed the halls of Congress in 2021, and since then many Trump loyalists have viewed him as a traitor.
The former vice-president said in March that Mr Trump's encouragement of the rioters had "endangered my family and everyone at the Capitol that day".
India’s economy will become carbon neutral by the year 2070, the country’s prime minster has announced at the COP26 climate crisis summit in Glasgow. The target date is two decades beyond what scientists say is needed to avert catastrophic climate impacts. India is the last of the world’s major carbon polluters to announce a net-zero target, with China saying it would reach that goal in 2060, and the United States and the European Union aiming for 2050.
China's carbon emissions are vast and growing, dwarfing those of other countries. Experts agree that without big reductions in China's emissions, the world cannot win the fight against climate change. In 2020, China's President Xi Jinping said his country would aim for its emissions to reach their highest point before 2030 and for carbon neutrality before 2060. His statement has now been confirmed as China's official position ahead of the COP26 global climate summit in Glasgow. But China has not said exactly how these goals will be achieved.

A crucial U.N. conference heard calls on its first day for the world's major economies to keep their promises of financial help to address the climate crisis, while big polluters India and Brazil made new commitments to cut emissions. World leaders, environmental experts and activists all pleaded for decisive action to halt the global warming which threatens the future of the planet at the start of the two-week COP26 summit in the Scottish city of Glasgow on Monday. The task facing negotiators was made even more daunting by the failure of the Group of 20 major industrial nations to agree ambitious new commitments at the weekend.
