Meryl Streep let out a guttural scream as she rallied in support of Hillary Clinton's bid to become America's first woman president.
The Hollywood actress, who won an Oscar for playing Britain's first female prime minister Margaret Thatcher in The Iron Lady, called on Democrats to get behind their nominee as she takes on Republican rival Donald Trump for the White House.
To loud cheers, Streep told the crowd at the Democratic National Convention in Philadelphia: "We've got some fight left in us don't we."
Khizr Khan got huge cheers as he challenged Donald Trump to "read the US constitution" and accused him of "sacrificing nothing" for America.
Clinton needs to win over doubters all over the USA. We joined a family of sceptical and divided voters to see if her message hit home.
The historic Democrat nominee's key message sought to resonate with her opponents as well as her supporters. But it also raised questions.
