The Note: New Mueller wait game looms over Trump

The TAKE with Rick Klein

Things could get interesting all over again.

If Attorney General William Barr was seeking to dispel mystery about what isn't known about special counsel Robert Mueller's final report, he didn't accomplish it on Capitol Hill Tuesday.

"The bottom line is binary, which is: charges or no charges," Barr said, promising a redacted version of the report inside the next week.

Prosecuting or not is one line, but one that may have been written from the start. The Justice Department was always exceedingly unlikely to bring a case against the president, if based only on the department's legal interpretation that a sitting president cannot be charged.

Mueller's top lines are not yet known and Barr hasn't expanded on his initial four-page letter. They will be filled out by the final report and the political judgments that stem from it.

Recall Barr's letter said that regarding potential obstruction of justice by President Donald Trump, "most" of the information found by Mueller has been "the subject of public reporting," suggesting some isn't yet known.

It also means that snap judgments about what Mueller did or didn't find are all subject to revision in the days ahead.

The RUNDOWN with MaryAlice Parks

Wednesday is the deadline for the Internal Revenue Service to respond to House Democrats' request for information on the president's taxes and any potential audit, but Trump's returns are not the only ones in the news this week.

Sen. Bernie Sanders, whose campaign appears to have brought in the largest donation haul in the first quarter, has faced questions about having not yet released his own tax returns. Many of his Democratic primary opponents have.

During a New York Times interview Tuesday, the Vermont senator pledged to release 10 years of returns next week, while admitting he's now a millionaire.

Sanders had likely hoped to focus on re-introducing his Medicare-for-all legislation this week. So far, 15 senators have signed on as co-sponsors, including Sens. Cory Booker, D-N.J., Kirsten Gillibrand, D-N.Y., Kamala Harris, D-Calif., and Elizabeth Warren, D-Mass., who are all running for president.

But this pitch of his, designed in part to help vulnerable populations, could be overshadowed by headlines about his own finances.

The TIP with Will Steakin

Former U.S. Rep. John Delaney was the first Democrat to enter the race for the White House nearly two years ago. He currently has $10 million in cash on hand from his personal finances, according to a senior campaign official, and he's just one national poll away from making the debate stage.

While he's yet to cross the new fundraising bar set by the Democratic National Committee to get onto the debate stage, his campaign told ABC News it's "confident" the former Maryland congressman will make the cut by soon reaching 1% support in a third national survey.

His $10 million should help sustain his bid while other candidates scramble to raise money within an ever-expanding and competitive fundraising field. As a point of comparison, Sen. Amy Klobuchar, D-Minn., finished the first quarter with $7 million in the bank.
