US intelligence has confirmed that Iran was behind the hacking of Donald Trump's presidential campaign.
The FBI and other agencies said Iran's goal was to disrupt the election and undermine confidence in democracy.
The Trump campaign received a spear-phishing email, which is a fake message designed to trick people into clicking on a malicious link.
The intelligence community believes Iran targeted both parties, aiming to influence the election through data theft and leaks, potentially to gain an advantage.
