INDIANAPOLIS • Ms Carly Fiorina was so happy to be named United States presidential hopeful Ted Cruz's running mate, she broke into song during her acceptance speech. But the chorus that greeted her on social media was anything but complimentary.

Mr Cruz announced at a rally on Wednesday in Indianapolis that the former Hewlett-Packard chief executive would join his ticket. But the unveiling faced scorn on social media after she started to sing while addressing the crowd.

"I know two girls that I just adore," crooned Ms Fiorina, in reference to Mr Cruz's two daughters, Caroline and Catherine. "I'm so happy I can see them more. 'Cuz we travel on the bus all day; we get to play."

Twitter users mocked Ms Fiorina, 61, over her singing.

"Carly Fiorina started singing at a rally where she's named VP by a candidate who ain't getting the nod," tweeted writer and Ebony columnist Michael Arceneaux (@young- sinick).

"You know this was a joke but then she literally went and sang at the event," tweeted joseito (@go-oat).
