President Donald Trump's lawyers argued on Monday that the impeachment case against him is a product of a rigged process by
Democrats and "must be rejected" in the
Senate trial that gets under way in earnest on Tuesday.

An executive summary of Trump's pre-trial brief for the Senate proceedings urges the Republican-led Senate to quickly acquit the president on two articles of impeachment approved against him by the Democratic-controlled House of Representatives.
"The Senate should speedily reject these deficient articles of impeachment and acquit the president," said the summary, released on Monday.
