Andrew Jackson served his term under plenty of scrutiny after it turned out his wife was still married. He had married her under the assumption that she was divorced

Rather than having to do directly with the President, this scandal merely occurred during his reign. Secretary of the Interior Albert B. Fall abused his power to give drilling rights for the Teapot Dome Reserve to the Mammoth Oil Company in return for bribes. When the scandal came to light in 1924, he had collected over 100,000 in kickbacks from the Mammoth Oil Company, among others. Although Harding had passed away in office before the scandal came to life, it became a topic of much discussion for years after his death and continues to haunt his now infamous legacy.

LBJs mistake lay in underestimating the Vietcongs tenacity and endurance, and also the lack of a firm, clear and suitable Vietnam War strategy. While US forces used more traditional tactics and were often ill-equipped for the terrain, the Viet Cong wreaked havoc by refusing to hold permanent positions hiding, attacking then vanishing once again. Using this rather daring but effective tactic, a Third World nation was able to gain a substantial advantage over a leading military superpower.

This was a juicy scandal that hit Grover Cleveland when he was running for the presidency in 1884. A woman named Maria C. Halpin, a widow with whom he had had a relationship, named him as the father to her son. On receiving the claim, he agreed to support the child and even agreed to place him in an orphanage when she was no longer in a position to raise him. He was open and honest about the entire episode, which surprisingly helped him in his election. The revelation of the issue gave birth to the chant Ma, Ma, wheres my Pa? Gone to the White House, ha, ha, ha!,

In 1802, Jefferson was accused of having an intimate relationship with his slave, Sally Hemings. To top it off, he was also rumored to have had a child with her. He vehemently denied the allegations, and remained president for the next 7 years. In the later years, DNA evidence pointed to the likelihood of Jefferson having fathered Hemings children.

The Watergate scandal is one of the all-time biggest involving a serving US President. Watergate broke when five men were caught while breaking into the Democratic National Headquarters located at the Watergate business complex, in 1972. An investigation into this break in and the one at Daniel Ellsbergs psychiatrists office Ellsberg had published the secret Pentagon Papers revealed the cover up that Richard Nixon and his advisors had attempted. Nixon resigned on 9th August 1974, before he could be impeached.

The Bay of Pigs Invasion was a futile exercise by United States-backed Cuban exiles to overthrow the government of the Cuban dictator Fidel Castro. After the increased conflict between U.S. government and Castros leftist regime led President Dwight D. Eisenhower to break off diplomatic relations with Cuba in January 1961, the invasion plan was approved by Eisenhowers successor, John F. Kennedy. The US-backed forces suffered a decisive and clear defeat, causing strong embarrassment for the Kennedy Administration.

He broke international agreements and helped fund a revolution. He supplied weapons to Iran, breaking an arms embargo. Then he used the gains to fund a revolutionary group called Contras in Nicaragua on the sly, which was in violation of Borland Agreement. The uproar that followed this incident ended in major Congressional hearings. Reagan is a beloved former President but many still point to these events as a marker of a man willing to break the rules when it suited him.

STILL IN MY OPINION THE BEST PRESIDENT EVER.....BUT....Charming and suave, Clinton met his Waterloo thanks to alleged sexual shenanigans with White House intern Monica Lewinsky. The scandal that followed allegations of sexual misconduct drew major reactions from the world over. His repeated denials of any misconduct only added to the outrage. It resulted in a vote to impeach him by the House of Representatives in 1998. The Senate did not vote to oust him from office but this incident left an indelible mark on his presidency.
