US Republican presidential candidate Ted Cruz's campaign is vetting former business executive Carly Fiorina as a possible vice presidential pick, ABC News is reporting.

Earlier, Cruz's campaign said it had narrowed its running mate options to a short list.

Fiorina, a former CEO of Hewlett Packard, dropped out of the presidential race in February.
