The Note: Has Trump had his 'heckuva job' moment with Puerto Rico? Trump is now praising FEMA for its response to Puerto Rico.

 -- THE TAKE with ABC News' Rick Klein

The first two storms, it appears, were only wind-ups to the presidential moment that presents itself now. The crisis in Puerto Rico figures to define President Trump's responses to this remarkable string of powerful storms. After first seeming to blame Puerto Rico's poor infrastructure and fiscal crises, Trump is now praising FEMA and expressing his wish that the "press would treat fairly." But this is one where claims of "fake news" will likely be subsumed by the images and realities. Those realities include millions of American citizens in total crisis. Sen. Marco Rubio, R-Fla., is warning that the lack of "clear command, control and communication" will cause the situation to "deteriorate rapidly." The general who oversaw the federal response to Hurricane Katrina is calling the situation – yes – "like Katrina." This is a heckuva comment, from acting Homeland Security Secretary Elaine Duke: "I know it is really a good news story in terms of our ability to reach people and the limited number of deaths." Maybe she will be proven right, and Trump will be praised for taking charge. But this will require a lightly staffed administration – led by a president prone to distraction – to do a whole lot of difficult work, and fast.

5 unanswered questions about the Trump tax plan. The release of a more detailed outline of what President Donald Trump and the White House have in mind for a tax overhaul has provided some new information but left many unanswered questions.

Senate leader: Twitter presentation on election interference "deeply disappointing." After three executives from the company met with leaders on Capitol Hill, Virginia Sen. Mark Warner, the ranking Democrat on the Senate Intelligence Committee, told reporters that Twitter's presentation to investigators was "deeply disappointing." "Their response was frankly inadequate on almost every level," Warner said. "I'm more than a bit surprised that anyone from the Twitter team would think that the presentation they made to the Senate staff today even began to answer the kind of questions we'd asked. So there is a lot more work they need to do." http://abcn.ws/2wYrGil
