Democrats in the U.S. House of Representatives announced impeachment charges against President Donald Trump on Tuesday, making him the fourth president in U.S. history to face a formal effort to remove him from office.

The Democratic-controlled House is almost certain to vote to impeach the president as soon as next week, setting up a trial in the Republican-led Senate early next year, shortly before the presidential election kicks off with primaries in Iowa and New Hampshire.

The effort to force Trump out of the White House faces long odds of success. At least 20 Senate Republicans would have to vote to remove him from office, and none so far have indicated they are considering such a move. 

He is the fourth U.S. president to face impeachment.

Democratic President Bill Clinton was impeached in 1998 for lying about a sexual relationship he had with a White House intern, but he was acquitted in the Senate. Republican President Richard Nixon resigned in 1974 before he was impeached over his involvement in the Watergate scandal. Democratic President Andrew Johnson was impeached in 1868 but not convicted in the Senate.
