On the domestic front, Trump signed a tax cut for individuals and corporations and reduced federal regulations, and oversaw a continuation of a strong economy that followed the last decade's recession and the lowest unemployment rates in decades. Republicans in Congress pushed to repeal and replace the Affordable Care Act, ultimately failing to pass a replacement, while repealing the law's individual health insurance mandate as part of their 2017 tax cut legislation. Throughout his term, Trump pushed to secure the United States-Mexico border and curb illegal immigration. Some of his immigration policies ("Muslim ban", family separations at Southern border, advocacy for a transcontinental border wall) were subject of controversy. In foreign policy, Trump sought to renegotiate trade deals with the United States–Mexico–Canada Agreement replacing NAFTA, and a Phase 1 trade deal with China as part of an ongoing trade war, among others. The Trump administration withdrew the United States from the Iran Nuclear Deal signed under the Obama administration, sought to denuclearize the Korean Peninsula - meeting with North Korean leader Kim Jong Un in Singapore, in Vietnam, and at the DMZ, moved the US Embassy in Israel to Jerusalem recognizing Jerusalem as the capital of Israel, brokered a peace agreement between Israel and the United Arab Emirates, and pressured European nations in NATO to increase their defense spending. In 2018, Democrats regained control of the House of Representatives, sending its most diverse delegation to date, including a record number of women, while Republicans added slightly to their Senate majority.
