Good morning, NBC News readers.

"Sometimes you have to walk and I think that was one of these times."

That's what President Donald Trump said at a hastily rescheduled news conference after he abruptly broke off his nuclear summit with North Korean leader Kim Jong Un early Thursday.

From Hanoi to more fallout from Michael Cohen's testimony on Capitol Hill, here's what we're watching today.

North Korea nuclear summit ends without agreement

A planned working lunch and signing ceremony were suddenly cancelled as Trump and Kim’s negotiations collapsed.

The president said the sticking point that doomed the talks was Kim's demand that the U.S. lift all sanctions before denuclearization.

"Basically they wanted the sanctions lifted in their entirety, and we couldn't do that," Trump said.

However, the president insisted that the meeting ended on "warm" and "very friendly" terms with a handshake.

And he still had words of praise for the dictator Kim, saying he took him "at his word" when Kim claimed he had nothing to do with the death of American Otto Warmbier.

News analysis: Trump lost big today, but it could've been a lot worse, NBC News' Jonathan Allen writes.

'I am not protecting Mr. Trump anymore'

Michael Cohen, the president's longtime fixer and personal attorney, painted a scathing portrait of his former boss during a blockbuster hearing before the House Oversight Committee on Wednesday that lasted more than seven hours.

Cohen expressed remorse for his actions and past loyalty to Trump.

Democrats, who now control the committee, mostly asked Cohen questions about alleged criminal conduct by Trump while Republican members on the committee largely sought to discredit and delegitimize his testimony.

At one point Rep. James Comer, R-Ky., challenged the former lawyer's description of the president, saying: "Mr. Cohen, you called Donald Trump a cheat in your opening testimony. What would you call yourself?"

"A fool," Cohen replied.

Trump blasted Cohen's testimony during his press conference in Hanoi, saying it amounted to a "fake hearing." He did praise Cohen, however, for saying he had no direct evidence of collusion with Russia.

News analysis : One upshot from the extraordinary hearing was that no matter what special counsel Robert Mueller concludes from his investigation of Russian election interference, federal prosecutors in New York pose their own separate danger to the president and his business associates, NBC News' Ken Dilanian writes.
