Nikki Haley says she will be voting for Donald Trump in the November US election, a notable show of support given their intense and often personal rivalry during the Republican primary calendar.

But Haley also made it clear she feels Trump has work to do to win over voters who supported her during the course of the primary campaign and continue to cast votes for her in ongoing primary contests.

“I will be voting for Trump,” Haley, Trump’s former United Nations ambassador, said during an event at the Hudson Institute in Washington on Wednesday.

“Having said that, I stand by what I said in my suspension speech,” Haley added. “Trump would be smart to reach out to the millions of people who voted for me and continue to support me and not assume that they’re just going to be with him. And I genuinely hope he does that.”

The comments in her first public speech since leaving the race are another signal of the GOP’s virtually complete consolidation of support behind Trump, even from those who have labelled him a threat in the past.

Haley shuttered her own bid for the GOP nomination two months ago but did not immediately endorse Trump, having accused him of causing chaos and disregarding the importance of US alliances abroad as well as questioning whether Trump, 77, was too old to be president again.

Trump, in turn, repeatedly mocked her with the nickname “Birdbrain,” though he curtailed those attacks after securing enough delegates in March to become the presumptive Republican nominee.

Trump’s campaign did not immediately respond to a request for comment on Haley’s announcement.

President Joe Biden’s campaign, meanwhile, has been working to win over her supporters, whom they view as true swing voters. Biden’s team is quietly organising a Republicans for Biden group, which will eventually include dedicated staff and focus on the hundreds of thousands of Haley voters in each battleground state, according to people familiar with the plans but not authorised to discuss them publicly.

Despite Haley’s announcement Wednesday, the Biden campaign made it clear they

If she runs for president again, Haley will likely need to win over former Trump supporters in a Republican primary. But her support for him now risks offending moderates and anti-Trump conservatives.
