The White House will not participate in Congress' ongoing impeachment inquiry, it said Tuesday, stepping up a political and legal standoff between the executive and legislative branches of government.

In a blistering eight-page letter to Democratic congressional leaders, including House Speaker Nancy Pelosi, White House counsel Pat Cipollone repeatedly mocked the Democrats' process.

President Trump said Wednesday that the push for his impeachment is a "hoax," again denying any wrongdoing during a July call with Ukrainian President Volodymyr Zelenskiy during which he pushed for an investigation into former Vice President Joe Biden, a potential 2020 rival.

"No push, no pressure, no nothing — it's all a hoax, folks. It's all a big hoax," Trump said.

In an exclusive interview with NPR, House Speaker Nancy Pelosi says she has not changed her mind on pursuing impeachment but is ready to change the law to restrain presidential power and make it clear that a sitting president can, in fact, be indicted.

New York City Mayor Bill de Blasio ended his campaign for president on Friday morning, acknowledging that he was unable to successfully pitch his progressive ideas to the Democratic electorate.

"I feel like I have contributed all I can to this primary election. It's clearly not my time, so I'm going to end my presidential campaign," de Blasio said on MSNBC's Morning Joe.

De Blasio's exit makes him the sixth candidate to drop out of the field, bringing the total number of Democrats seeking the nomination to 19.

The Sept. 12 Democratic debate stage is set with just 10 candidates, ensuring there will be a one-night event in which the front-runners will finally come face to face.

The massive Democratic presidential field could begin its inevitable reduction this week with only half of the current candidates set to make the cut for next month's debate.

The controversial decision will please many party stalwarts who worry that the often dizzying number of Democrats seeking the nomination could endanger their chances of defeating President Trump.

Looking around the inaugural meeting of the Fort Bend County Young Democrats, there's clear evidence that the face of Texas is changing.

About 60 young adults — almost all minorities — are crammed into a side room of a bubble tea cafe in the Houston suburbs on a steamy August evening. As local and congressional candidates make their pitch to the new group, there are roaring cheers — and a sense of optimism that wasn't here even a decade ago.
