Evidence for impeaching US President Donald Trump for misconduct in office is "overwhelming", according to the panel leading the impeachment inquiry.
The president placed personal political interests "above the national interests of the United States", it states in a key report to House lawmakers.
He tried over months to "solicit foreign interference" from Ukraine to help his 2020 re-election bid, it adds.
The report is designed to lay out the case to remove Mr Trump from office.
He denies any wrongdoing, and has described the inquiry as a witch-hunt.
Before the draft report was released, the Republican president attacked the Democrat-led investigation as "very unpatriotic".
Following publication, White House press secretary Stephanie Grisham said the Democrats "utterly failed to produce any evidence of wrongdoing" and that the report "reflects nothing more than their frustrations".
Among formal impeachment charges expected to be considered are abuse of power, obstruction of justice and contempt of Congress.
What does the report say?
The Trump-Ukraine Impeachment Inquiry Report was made public on Tuesday by the House Permanent Select Committee on Intelligence.
It says the inquiry "uncovered a months-long effort by President Trump to use the powers of his office to solicit foreign interference on his behalf in the 2020 election".
"President Trump's scheme subverted US foreign policy toward Ukraine and undermined our national security in favour of two politically-motivated investigations that would help his presidential re-election campaign," it says.
"The president demanded that the newly-elected Ukrainian President, Volodymyr Zelensky, publicly announce investigations into a political rival that he apparently feared the most, former Vice-President Joe Biden, and into a discredited theory that it was Ukraine, not Russia, that interfered in the 2016 presidential election."
Evidence of misconduct is overwhelming "and so too is the evidence of his obstruction of Congress", the report says.
Striking new details
Anyone who listened to Adam Schiff's extended, extemporaneous closing statement at the impeachment hearings two weeks ago probably wouldn't be surprised by the summary of the Intelligence Committee report released on Tuesday. Buried within the pages of the 300-page document, however, were some striking new details.
The telecommunications company AT&T provided committee investigators with Rudy Giuliani's mobile phone records – and those records shed new light on the timing and breadth the communications Donald Trump's personal lawyer had with the White House.
Starting in April of this year, Giuliani had multiple phone conversations with numbers listed for the White House and, in particular, the Office of Management and Budget – the government agency ultimately responsible for putting a hold on the congressionally authorised US military aid to Ukraine.
While the details of these communications aren't known, their simple existence undercuts the contention of some presidential defenders that Giuliani was operating independently of senior administration officials.
Multiple witnesses, including US Ambassador to the EU Gordan Sondland, have testified that Giuliani was directing them, at the behest of the president, to pressure Ukrainian officials to open investigations that would be politically advantageous for Mr Trump.
Now the line between Giuliani and the White House has become more certain.
What happens next?
The intelligence committee is expected to vote along party lines later on Tuesday to approve its report summing up the evidence against President Trump.
The report will then be submitted to the House Judiciary Committee, which will start its own proceedings on Wednesday, hours before Mr Trump is due to return to Washington from the UK.
The judiciary panel's hearings will being with four constitutional scholars, who will explain how impeachment works.
The White House has refused to participate in the hearings, citing a lack of "fairness".
Democrats are keen to hold a vote on impeachment before the end of the year, setting a potential trial in the Senate perhaps as early as January.
Trump and impeachment
What are Republicans saying?
Before the draft report was made public, House Republicans released their own 123-page report that condemned the "unelected bureaucrats" who testified, saying they "fundamentally disagreed with President Trump's style, world view and decisions".
The document accuses Democrats of "trying to undo the will of the American people" and argues that they have been trying to depose the president since his first day in office.
"None of the Democrats' witnesses testified to having evidence of bribery, extortion, or any high crime or misdemeanours," it argues, in reference to the constitutional clause that permits the removal of a president.
