Document 3: Barack Obama: Der schwarze Kennedy: Barack Obama – Der schwarze Kennedy (English: Barack Obama – The black Kennedy ) is a best-selling German-language biography of President of the United States Barack Obama by journalist Christoph von Marschall. The book was written by Marschall while he spent much of 2007 travelling with Obama's presidential campaign as a reporter for the Berlin newspaper "Der Tagesspiegel". It covers Obama’s life from his childhood, through his college years, his time as a community organizer in Chicago, Illinois, and his political career including his 2008 presidential campaign.

Document 4: Assassination threats against Barack Obama: Some of the threats have been extended to members of Obama's family, including First Lady Michelle Obama. Obama and his officials have generally declined to discuss death threats against him since entering the presidential race. Some commentators have suggested the unusually high number of death threats surrounding Obama are at least partially tied to the use of racist imagery and words used by some of Obama's critics to describe the president. In 2009 journalist Ronald Kessler reported that Obama received 400 percent more death threats than his predecessor. Later that year, the Secret Service stated that the volume of threats against Obama was "comparable to that under George W. Bush and Bill Clinton."

Following recent tradition, Speaker of the House John Boehner sent a letter on December 19, 2014, formally inviting President Obama to speak (despite a proposal from some conservatives that House Republicans withhold the invitation in retaliation for Obama's executive actions on immigration reform).

Webcasts were also provided by other sponsors, including a webcast from the U.S. Republican Party.
Document 7: Healthcare reform debate in the United States: The healthcare reform debate in the United States has been a political issue focusing upon increasing medical coverage, decreasing costs, insurance reform, and the philosophy of its provision, funding, and government involvement. Following the election of Barack Obama as president, who campaigned heavily on accomplishing health care reform, the Patient Protection and Affordable Care Act (PPACA) was enacted in March 2010. However, in the next election of Donald Trump as president, he campaigned to repeal and replace Obamacare and came up with a seven-point plan for healthcare reform. With this seven point plan President Trump discussed that the healthcare system would work based on free market principles. According to Ballotpedia, he stated that he would repeal Obamacare, reduce barriers to the interstate sale of health insurance, institute a full tax deduction for insurance premium payments for individuals, make Health Saving Accounts inheritable, require price transparency, block-grant Medicaid to the states, and allow for more overseas drug providers through lowered regulatory barriers. Trump added that enforcing immigration laws could reduce healthcare costs. However, this seven point plan has not taken the place of Obamacare, and it is possible that Obamacare will not be repealed but instead it will be modified so that all parts of this plan work accordingly.

No list of articles of impeachment was ever drawn up and proposed to the Judiciary Committee.
