That WaPo article on Sonland's testimony is really bad for Trump. It's worth reading the whole thing. Some other excerpts:
The Sept. 9 exchange between Sondland and the top U.S. diplomat to Ukraine has become central to the House Democrats’ impeachment inquiry into whether the president abused his office in pressuring Ukraine to open an investigation into his political rival Joe Biden and his son, who sat on the board of a Ukrainian energy company. The White House and its defenders have held up Sondland’s text, which included “no quid pro quo’s of any kind,” as proof that none was ever considered.
Sondland is expected to say that for months before the Sept. 9 message, he worked at the direction of Rudolph W. Giuliani, Trump’s personal attorney, to secure what he would call in another text message the “deliverable” sought by Trump: a public statement from Ukraine that it would investigate corruption, including mentioning Burisma, a Ukrainian energy company, by name. In exchange for the statement, the president would grant Ukraine’s new president a coveted White House audience.

Sondland’s testimony will raise the possibility that Trump wasn’t truthful in his denial of a quid pro quo as well as an alternative scenario in which the president’s interest in the scheme soured at a time when his administration faced mounting scrutiny over why it was withholding about $400 million in security assistance to Ukraine and delaying a leader-level visit with Ukrainian President Volodymyr Zelensky.
“Whether he’s deciding it’s getting too hot to handle and he backs off whatever his position really was a month earlier, I don’t know,” the person said of Sondland’s understanding.

“It was a quid pro quo, but not a corrupt one,” the person familiar with Sondland’s testimony said.
Sondland appears poised to say that he and other diplomats did not know that the request to mention Burisma was really an effort to impugn the reputations of Biden and his son Hunter, who had served as a Burisma board member. Sondland contends that he didn’t know about the Biden connection until a whistleblower complaint and transcript surfaced in late September.
To trust Sondland’s testimony, members of Congress will have to believe Sondland had not seen televised appearances by Giuliani over the spring and summer, or numerous newspaper and magazine articles questioning whether Hunter Biden’s role at Burisma could prove to be a drag on his father’s presidential campaign.
“If people find that incredulous, it strikes me that the incredulity is hindsight bias,” said the person familiar with Sondland’s testimony. “The things that seem so clear to people now didn’t seem so clear in real time.”
The testimony by Sondland, a Portland hotelier who gave $1 million to Trump’s inaugural committee through four of his limited liability companies, could prove damaging to Giuliani and the president.
For months, Sondland’s deep involvement in issues related to Ukraine struck diplomats in Brussels and Washington as highly unusual, given his role as envoy to the European Union, a large trade bloc that does not include Ukraine. Former U.S. officials have said Sondland viewed the Ukraine assignment as critical to winning Trump’s favor and auditioning for a more senior job in the administration.
