Biden's words were spread by his campaign headquarters, writes CNN.

Commenting on Nikki Haley's decision to withdraw from the presidential race, Biden noted that she was ready to "tell the truth" about Trump, in particular about his "inability to distinguish between good and evil."

“And also about how he cowers before Putin,” he said.

On March 6, Nikki Haley withdrew from the race for the right to run for US President from the Republican Party.

After this, the Associated Press reported that Trump became the only Republican contender for the US presidency.
