The Trump administration threatened to block federal aid to Alaska in&nbsp;an effort to bully one of the Republican senators opposed to the current Senate GOP push to roll back the Affordable Care Act, according to a report by the Alaska Dispatch News.The news site reports&nbsp;that Interior Secretary Ryan Zinke on Wednesday called Alaska Sens. Lisa Murkowski and&nbsp;Dan Sullivan with a warning that Murkowski&rsquo;s vote &ldquo;had put Alaska's future with the administration in jeopardy.&rdquo;According to the report:&nbsp;Sullivan said the call from Zinke heralded a "troubling&nbsp;message.""I'm not going to go into the details, but I fear that the strong economic growth, pro-energy, pro-mining, pro-jobs and personnel from Alaska who are part of those policies are going to stop," Sullivan said."I tried to push back on behalf of all Alaskans. &hellip; We're facing some difficult times and there's a lot of enthusiasm for the policies that Secretary Zinke and the president have been talking about with regard to our economy. But the message was pretty clear," Sullivan said.The threat followed disparaging comments made by the president about Murkowski, including a Twitter attack Wednesday morning"Senator @lisamurkowski of the Great State of Alaska really let the Republicans, and our country, down yesterday. Too bad!" Trump wrote.Murkowski dismissed the president&rsquo;s attacks in an interview with MSNBC."We're here to govern. We're here to legislate,&rdquo; she said. &ldquo;We're here to represent the people who sent us here. And so every day shouldn't be about campaigning. Every day shouldn't be about winning elections. How about just doing a little bit of governing around here? That's what I'm here for."Murkowski and Maine Sen. Susan Collins were the only Republicans who voted against a procedural motion Tuesday to begin debating legislation rolling back the 2010 healthcare law, often called Obamacare.Sullivan, also a Republican, voted in favor of advancing the bill.Murkowski has urged a more open process to develop the legislation, which Senate Majority Leader Mitch McConnell (R-Ky) has&nbsp;put together behind closed doors without committee hearings or input from Democrats.A spokeswoman for Zinke did not immediately respond to a request for comment.
