(Reuters) - Financial market concerns are rising about the pace of policymaking in Washington under U.S. President Donald Trump and fellow Republicans in Congress, with investors focused on knock-on effects from any setbacks in Trump’s Obamacare rollback plan. Trump set sky-high expectations on the campaign trail and after taking office, not only for repealing and replacing Obamacare but also for cutting taxes, reducing business regulations and boosting infrastructure. After eight weeks in power, Trump has not introduced any major legislation or won passage of legislation he favors. The Republican healthcare bill he supports was facing resistance from members of his own party, as well as Democrats, ahead of a  vote on it expected in the House of Representatives on Thursday. Market analysts have been expecting Trump and the Republicans to complete confirmation of his Supreme Court nominee by early April; repeal Obamacare by mid-May; pass a budget resolution by late June; and reform the tax code by year-end. Analysts this week expressed doubt about those targets. Here is a look at key 2017 dates coming up on the Washington policy calendar that could influence Trump’s agenda.
