One hundred senators will cast votes on Feb. 5 in the impeachment trial against President Donald Trump, bringing the months-long process to a close.

The impeachment inquiry in the House of Representatives started in September and culminated with the impeachment of Trump by the Democrat-controlled House in December. The impeachment trial started last month in the Republican-controlled Senate.
