Donald Trump on Wednesday became the third U.S. president to be impeached as the House of Representatives formally charged him with abuse of power and obstruction of Congress in a historic step that will inflame partisan tensions across a deeply divided America.

The Democratic-led House's passage of two articles of impeachment on a mostly party-line vote sets the stage for a trial next month in the Republican-controlled Senate- friendlier terrain for Trump- on whether to convict and remove him from office.

The abuse of power article was passed on a 230-197 vote. The obstruction article was passed by 229-198.
