A group of Roman Catholic nuns are taking an unusual bus ride across America.<br /><br />They are protesting against government budget cuts, which they say are harming low income families.<br /><br />A recent Vatican report criticised some nuns for focusing too much on economic injustice <br /><br />Even though the nuns were stung by the criticism from Rome, they decided to stay the course and say the firestorm has given them a platform.<br /><br />In their latest trip, the nuns are in Janesville, Wisconsin, to deliver an alternative budget to Republican House member Paul Ryan, in which they propose a plan that favours a safety net for the worst off instead of tax cuts for the rich.<br /><br />There is every sign they'll continue to take their gospel on the road, with or without the Vatican's blessing.<br /><br />Al Jazeera's Kristen Saloomey reports from Janesville, Wisconsin.
