Washington - After weeks of delay, the House of Representatives is expected on Wednesday to send impeachment charges against President Donald Trump to the Senate, clearing the way for that chamber to consider whether Trump should be removed from office.
The weeks-long trial in the Senate is expected to ultimately end in the president's acquittal. But it will focus attention on Trump's efforts to pressure Ukraine to investigate a political rival, former Vice President Joe Biden, as the 2020 presidential campaign begins in earnest.
Biden is one of 12 candidates vying for the Democratic nomination, and the trial might still be under way when Iowa and New Hampshire hold their first nominating contests in early February.
None of the Senate's 53 Republicans have voiced support for ousting Trump, a step that would require a two-thirds majority in the 100-member chamber.
Though the ultimate outcome is not in doubt, the trial could deliver some moments of drama.
