From Anthony Zurcher writing at the BBC:

The “lock her up” chants started early and came often at Donald Trump’s campaign event near Fort Lauderdale, Florida on Wednesday evening.

The mere mention of Democratic nominee Hillary Clinton elicited rounds of boos, angry shouts and the now-obligatory calls for incarceration.

Trump’s warm-up act, senior policy adviser Stephen Miller, told the cheering crowd that if President Barack Obama “really cared about national security”, he would indict Mrs Clinton.

The Democratic nominee wasn’t the only target of the evening’s ire, however.

When members of the media walked into the press area, more boos cascaded down, along with shouts of “liars”.
