The shifts in his campaign positions have pleased critics but upset some supporters. Trump has a history of modifying his positions during the campaign, so it is possible that he could change his stances again before or after his inauguration on Jan 20. One example of this is his stance on prosecuting Hillary Clinton. Initially, he vowed to prosecute her for her use of a private email server and alleged abuses of her position. However, in a New York Times interview on Nov 22, he indicated that he no longer wanted to pursue legal action against her, stating, "I want to move forward, I don’t want to move back." I do not wish to harm the Clintons. I truly do not want to hurt them. However, he declined to definitively rule out the idea of investigating Clinton. Trump has labeled climate change as a hoax, and during his campaign, he expressed a desire to withdraw the US from the 2015 Paris Agreement involving nearly 200 nations. Instead, he intends to focus on developing affordable coal, shale, and oil resources. According to a source from his transition team on November 12, Trump's advisers were exploring options to circumvent the standard four-year process for withdrawing from the climate agreement. During an interview with the Times on November 22, Trump expressed willingness to consider America's role in addressing climate change, stating, "I am open to it. We will carefully examine the issue." When asked about his views on human activity causing climate change, he acknowledged some connection, saying, "I believe there is some link." The amount of change will vary. Trump promised to repeal the Affordable Care Act during his campaign, calling it a disaster. He proposed replacing it with a plan that would give more control to states over Medicaid and allow insurers to sell plans nationwide. However, in an interview with the Wall Street Journal on Nov 11, Trump mentioned the possibility of keeping some parts of the law, such as the provision allowing parents to keep adult children on their insurance until age 26 and preventing insurers from denying coverage to those with pre-existing conditions. Trump stated that Obamacare will either be amended or completely replaced. During his campaign, Trump promised to build a wall along the US-Mexican border to reduce illegal immigration, have Mexico pay for it, and deport millions of illegal immigrants. He also proposed a temporary ban on Muslims entering the country to combat terrorism. Although he never retracted these statements, he later modified his proposal to temporarily suspend immigration from regions known for exporting terrorism and lacking safe vetting. In an interview with "60 Minutes," Trump confirmed his plans to build a wall, suggesting it could be a combination of wall and fence. He stated that he would use a fence for certain areas and a wall for others as he is skilled in construction. When questioned about deporting illegal immigrants, he mentioned focusing on those with criminal records, estimating the number to be around 2 to 3 million. Trump also expressed support for reviving waterboarding and other harsh interrogation methods for terrorism suspects, despite it being considered torture and banned under the Obama administration. During an interview with the New York Times on November 22nd, Trump mentioned that he was struck by Marine General James Mattis' response when asked about waterboarding. Mattis expressed that he found he performed better with cigarettes and beer than with torture. Trump noted that although this did not change his stance on the issue, he was impressed by the idea that waterboarding may not be as effective as some believe.
