‘Boycott Iowa’: latest twist in legal tussle between animal campaigners and US farmers

Twenty-five states have attempted to introduce legislation to chill animal rights activism, and six have succeeded, as a string of 'ag-gag' laws are overturned in courts

In retaliation, animal rights activists are calling on their supporters to boycott the state as a vacation destination.
