Former GOP presidential candidate Nikki Haley said Wednesday she will vote for former President Donald Trump in November.

During a question-and-answer session after delivering a speech at the Hudson Institute in Washington, D.C., on Wednesday, Haley was asked who she thinks would do a better job in the White House with national security issues: Joe Biden or Donald Trump.

The former United Nations ambassador said she prioritizes a president who will hold enemies to account, secure the border and support "capitalism and freedom" -- and that while "Trump has not been perfect on these policies," that "Biden has been a catastrophe."

"So, I will be voting for Trump," Haley said.

Haley suspended her campaign in March.

During a speech announcing her campaign suspension -- the day after suffering considerable losses on Super Tuesday, the former South Carolina governor said Trump had to "earn the votes."

"It is now up to Donald Trump to earn the votes of those in our party and beyond it, who did not support him," she said in March. "And I hope he does that. At its best politics is about bringing people into your cause, not turning them away. And our conservative cause badly needs more people."

Many of the Republicans who once challenged Trump for the nomination quickly fell into line behind him after exiting the race.

The Biden campaign has tried to court Haley voters, some of whom have told ABC News they remain undecided.

On Wednesday, following Haley's announcement, a representative of the Biden campaign released a statement touting their candidate.
