2018 was a tumultuous year in politics.

In the U.S., Donald Trump's second year in the presidency was marked by a series of firings among his senior staff, an immigration crisis at the border, and shootings that led to hundreds of protests and demonstrations nationwide.

2018 was also the year of a controversial Supreme Court nomination in which California psychology professor Christine Blasey Ford accused Trump nominee Brett Kavanaugh of sexual assault. Kavanaugh was ultimately confirmed to replace Justice Anthony Kennedy.

And, to top it all off, the November midterm election gave the House back to Democrats while Republicans got to keep the Senate. 

Internationally, leaders met during the G7 and G20 Summits, as well as at the FIFA Men's World Cup. Over the summer, Brazil elected Jair Bolsonaro as president, a man many have called the country's version of Donald Trump.

Meanwhile, Mexico elected Andrés Manuel López Obrador, a populist politician who pledged to end corruption and violence in the country and described Trump as "erratic and arrogant."
