Bill Clinton’s appearance at a Democrat rally has been turned into an attack ad by the Donald Trump campaign.

The former president joined the campaign trail on Sunday at a fish fry in Georgia, where he criticised the Republicans over the killing of Laken Riley, a Georgia nursing student who was murdered in February allegedly by an illegal migrant from Venezuela.

Mr Clinton rebuked Trump for blocking the Border Security Bill, which he suggested would have provided proper vetting of Ms Riley’s murderer, who crossed into the US in 2022 - under President Joe Biden’s administration.

“If they’d all been properly vetted that probably wouldn’t have happened,” he said of the Bill, which Senate Republicans voted against in May.

However, the two-term Democratic president’s comments have since been used for an attack ad by the Republican campaign, citing it as evidence to suggest not even Mr Clinton could defend the current administration’s border policies.

The ad missed out Mr Clinton’s earlier comments, in which he said that Ms Harris is “the only candidate who has actually endorsed a bill that would hold down immigration in any given year to a certain point”, adding: “Trump killed the bill.”
