Young undocumented immigrants seeking permanent status in the United States received an unexpected boost Thursday on Capitol Hill as a small group of House Republicans mounted a last-minute effort to bring up an immigration vote in Congress. The group of eight Republicans — some freed from political considerations by upcoming retirements and others facing tough re-elections races — defied their own party leadership, quickly persuading 10 more Republicans to sign on to a petition that would force debate on the Deferred Action for Childhood Arrivals (DACA) program. With all 193 Democrats expected to sign on, Republicans will have to persuade just seven more members of their own party to join the petition to trigger a vote on several immigration bills on the House floor. But Republican leadership said the effort would be wasted if the end result is a presidential veto. "I think it's important for us to come up with a solution that the president can support," House Speaker Paul Ryan told reporters Thursday. These types of petitions are rare and seen as a threat to leadership's ability to direct legislative action. "It's better to use the legislative process," Republican Majority Leader Kevin McCarthy told reporters Wednesday. But that argument appears to be losing sway with House members who see an opportunity for legislative action in a mid-term election year. The growing group of House Republicans are joining Democratic colleagues who have long criticized Ryan for not bringing immigration bills up for a vote. "This is about making sure we're not consolidating power in the White House," said Representative Mia Love, a Republican from Utah and one of the first lawmakers to sign petition. The immigration issue had all but died after an effort to pass a DACA fix collapsed in the U.S. Senate earlier this year. The program has been the focus of fierce negotiations on Capitol Hill since last September, when President Donald Trump announced he was ending the 2012 Obama-era program and called for a legislative fix. According to the above context, answer the following question. When did Trump call for a legislative fix?
Select from: (i). when 2012 Obama-era DACA was started; (ii). not enough information; (iii). before he ended the 2012 Obama-era DACA program; (iv). after he ended the 2012 Obama-era DACA program;
(iv).
