Today is Friday, Dec. 18, the 353rd day of 2020. There are 13 days left in the year.

Todayís Highlight in History:

On Dec. 18, 1865, the 13th Amendment to the Constitution, abolishing slavery, was declared in effect by Secretary of State William H. Seward.

On this date:

In 1915, President Woodrow Wilson, whose first wife, Ellen, had died the year before, married Edith Bolling Galt, a widow, at her Washington home.

In 1917, Congress passed the 18th Amendment to the U.S. Constitution prohibiting ìthe manufacture, sale, or transportation of intoxicating liquorsî and sent it to the states for ratification.

In 1940, Adolf Hitler signed a secret directive ordering preparations for a Nazi invasion of the Soviet Union. (Operation Barbarossa was launched in June 1941.)

In 1944, the U.S. Supreme Court upheld the governmentís wartime evacuation of people of Japanese descent from the West Coast while at the same time ruling that ìconcededly loyalî Americans of Japanese ancestry could not continue to be detained.

In 1956, Japan was admitted to the United Nations.

In 1957, the Shippingport Atomic Power Station in Pennsylvania, the first nuclear facility to generate electricity in the United States, went on line. (It was taken out of service in 1982.)

In 1987, Ivan F. Boesky was sentenced to three years in prison for his role in a major Wall Street insider-trading scandal. (Boesky served about two years of his sentence).

In 1998, the House debated articles of impeachment against President Bill Clinton. South Carolina carried out the nationís 500th execution since capital punishment resumed in 1977.

In 2000, the Electoral College cast its ballots, with President-elect George W. Bush receiving the expected 271; Al Gore, however, received 266, one fewer than expected, because of a District of Columbia Democrat whoíd left her ballot blank to protest the districtís lack of representation in Congress.

In 2003, two federal appeals courts ruled the U.S. military could not indefinitely hold prisoners without access to lawyers or American courts.

In 2008, W. Mark Felt, the former FBI second-in-command whoíd revealed himself as ìDeep Throatî three decades after the Watergate scandal, died in Santa Rosa, Calif., at age 95.

In 2018, the Trump administration banned bump stocks, the firearm attachments that allowed semi-automatic weapons to fire like machine guns, and gave gun owners until late March to turn in or destroy the devices. The president authorized the Defense Department to create a new Space Command, an effort to better organize and advance the militaryís operations in space.

Ten years ago: The U.S. Senate approved repeal of the militaryís 17-year ìdonít ask, donít tellî ban on openly gay troops in a 65-31 vote. (President Barack Obama later signed it into law.) Skier Lindsey Vonn was named the 2010 Female Athlete of the Year as chosen by members of The Associated Press.

Five years ago: Congress ended a chaotic year on a surprising note of bipartisan unity and productivity as it overwhelmingly approved a massive 2016 tax and spending package and sent it to President Barack Obama, who promptly signed it. United Nations Security Council members unanimously approved a resolution endorsing a peace process for Syria.

One year ago: The U.S. House impeached President Donald Trump on two charges, sending his case to the Senate for trial; the articles of impeachment accused him of abusing the power of the presidency.
