VOA常速英语:特朗普弹劾审判已正式开启

U.S. lawmakers managing the impeachment case against President Donald Trump filed a brief on Saturday laying out their arguments supporting charges of abuse of power and obstruction of Congress against the president.
In the 111-page document, the lawmakers summarized arguments made during weeks of testimony late last year during the House impeachment investigation.
They also called for Trump's removal in order to safeguard the integrity of this year's general election, in which Trump is seeking a second term as well as the U.S. system of government.
The president's legal team issued a rejection of the House's impeachment, calling the charges against Trump a dangerous attack on Americans and their right to vote.
Trump's impeachment trail starts Tuesday in the U.S. Senate.

Iran is sending the black boxes of the Ukrainian passenger plane that its military accidentally shot down this month back to Ukraine.
According to Tasnim news agency, Iranian authorities are also prepared for experts from France, Canada and the U.S. to examine the data from the boxes.
All 176 people aboard the Ukraine International Airlines flight died when the plane was shot down on January 8 shortly after takeoff from Tehran en route to Kyiv.
The director in charge of accident investigations at Iran's Civil Aviation Organization told Tasnim that the flight data recorder will be sent to France if experts could not read it in Kyiv.
That's Reuters' Lauren Anthony reporting.
