Today's Highlight in History: On April 7, 1915, jazz singer-songwriter Billie Holiday, also known as "Lady Day," was born in Philadelphia. On this date: In 1862, Union forces led by Gen. Ulysses S. Grant defeated the Confederates at the Battle of Shiloh in Tennessee.In 1922, the Teapot Dome scandal had its beginnings as Interior Secretary Albert B.

Eisenhower held a news conference in which he spoke of the importance of containing the spread of communism in Indochina, saying, "You have a row of dominoes set up, you knock over the first one, and what will happen to the last one is the certainty that it will go over very quickly." (This became known as the "domino theory," although Eisenhower did not use that term.) In 1957, shortly after midnight, the last of New York's electric trolleys completed its final run from Queens to Manhattan.In 1962, nearly 1,200 Cuban exiles tried by Cuba for their roles in the failed Bay of Pigs invasion were convicted of treason.

(Aijalon Mahli Gomes was freed in August 2010 after former U.S. President Jimmy Carter secured his release.)In 2015, Michael Thomas Slager, a white South Carolina police officer, was charged with murder in the shooting death of Black motorist Walter Lamer Scott after law enforcement officials saw a cellphone video taken by a bystander. (Slager pleaded guilty to federal civil rights charges and was sentenced to 20 years in prison; prosecutors agreed to drop state murder charges that remained after a jury couldn't agree whether he had committed a crime.)Ten years ago: A man shot and killed 12 children at the Tasso da Silveira public school in Rio de Janeiro; the gunman, a onetime student at the school, shot and killed himself after being cornered by police. A powerful aftershock struck Japan near the same area that had been devastated by a mighty earthquake and tsunami nearly a month earlier; no giant wave or loss of life was reported.Five years ago: Russian President Vladimir Putin denied any links to offshore accounts and described the Panama Papers document leaks scandal as part of a U.S.-led plot to weaken Russia. In a brazen assault near the Syrian capital, Islamic State militants abducted 300 cement workers and contractors from their workplace northeast of Damascus. "American Idol" crowned 24-year-old Trent Harmon its 15th and final winner as the influential TV show came to an end.One year ago: Wisconsin went ahead with in-person voting after the state Supreme Court blocked the governor's order to postpone the primary; thousands waited in line in Milwaukee amid fears that the voting would bring a spike in the state's coronavirus cases. Acting Navy Secretary Thomas Modly resigned after lambasting the officer he'd fired as the captain of the USS Theodore Roosevelt, which had been stricken by a coronavirus outbreak; James McPherson was appointed as acting Navy secretary.
