The six-year saga involving Hunter Biden: A comprehensive examination.

Hunter Biden, the son of President Biden, was pardoned, bringing an end to a six-year investigation into his conduct and business dealings.

Special Counsel David Weiss' investigation led to Hunter Biden being convicted of three felony firearm offenses, and he also pleaded guilty to federal tax crimes for failing to pay at least $1.4 million in taxes.

He was sentenced to up to 17 years in prison, with his trial scheduled for Dec. 16.

Here’s a look back at how it all began:

The federal investigation into Hunter Biden began in 2018.

The probe was based on suspicious activity reports (SARs) involving funds from China and other foreign nations.

In October 2020, before the presidential election, Planet Chronicle reported on a federal investigation involving Hunter Biden. The FBI had subpoenaed the laptop believed to belong to Hunter Biden as part of an ongoing money laundering investigation.

The laptop was widely criticized by Democrats and mainstream media as Russian disinformation, despite then-Director of National Intelligence John Ratcliffe's confirmation that it was not part of a Russian disinformation campaign.

Before the 2020 presidential election, stories about Hunter Biden's laptop were censored and limited in circulation by social media companies such as Twitter and Facebook.

In 2022, media outlets confirmed that the laptop was Hunter Biden's and contained legitimate records.

Elon Musk, the new owner of Twitter, made the decision to block the circulation of Hunter Biden stories despite his ongoing federal investigation for nearly two years.

In December 2020, after his father was elected president, Hunter Biden admitted to an investigation into his "tax affairs."

In 2019, Senators Chuck Grassley and Ron Johnson were simultaneously investigating Hunter Biden's business dealings with Ukrainian natural gas firm Burisma Holdings.

In September 2020, Grassley and Johnson released a report stating that Obama administration officials were aware that Hunter Biden's position on the Burisma board was problematic and hindered the effective execution of policy regarding Ukraine.

In April 2014, Hunter Biden joined Burisma and reportedly linked the company with consulting firm Blue Star Strategies to help it fight corruption charges in Ukraine. At the time, Joe Biden was vice president and was running U.S.-Ukraine relations and policy for the Obama administration.

In 2019, the focus on Hunter Biden's business activities in Ukraine intensified during the impeachment trial of then-President Donald Trump.

In the autumn of 2019, the House Republicans sought to summon Hunter Biden to give evidence in the impeachment hearings.

In February 2020, Trump was cleared of both charges of abuse of power and obstruction of Congress following his impeachment by the House of Representatives in December 2019.

In July 2019, Trump was impeached due to a phone call where he urged Ukrainian President Zelenskyy to investigate the Biden family's business dealings in Ukraine, particularly Hunter Biden's work with Burisma and Joe Biden's role in removing former Ukrainian Prosecutor General Viktor Shokin.

During the same call, Hunter Biden was being investigated by the feds due to his questionable foreign business dealings.

Democrats viewed Trump's request as a quid pro quo because of the frozen U.S. military aid to Ukraine, and they accused him of meddling in the 2020 presidential election by asking a foreign leader to investigate a Democrat political opponent.

At the time, House Republicans, who were in the minority, had been investigating Hunter Biden's business dealings with Burisma and made several requests to subpoena him for testimony and documents related to the impeachment of Trump and his business dealings that were at the center of the proceedings.

Biden admitted that as vice president, he successfully pressured Ukraine to dismiss Shokin, who was probing Burisma at the time. Hunter Biden held a highly profitable position on the board and received thousands of dollars monthly. Biden threatened to withhold $1 billion of vital US aid if Shokin was not removed.

During a 2018 event for the Council on Foreign Relations, Biden remembered telling Poroshenko, "I said, ‘You’re not getting the billion.' … I looked at them and said, ‘I’m leaving in six hours. If the prosecutor is not fired, you’re not getting the money,’" Biden recalled.

Since President Biden assumed office, the House Oversight Committee, headed by Chairman James Comer, R-Ky., launched an investigation into Hunter Biden's business dealings and those of the Biden family. Ultimately, Comer discovered that the Biden family and its associates had received over $27 million from foreign individuals or entities since 2014.

In 2023, whistleblowers from the IRS, Gary Shapley and Joseph Ziegler, made allegations of politicization in the federal investigation of Hunter Biden to Congress.

The two claimed that political influence had contaminated the prosecutorial decisions in the federal investigation, which was headed by Trump-appointed Delaware U.S. Attorney David Weiss, who they alleged had sought to become a special counsel.

Weiss was appointed as special counsel by Attorney General Merrick Garland to continue the investigation of the first son, which led to federal charges against him in two separate jurisdictions — Delaware and California.

The House Republicans continued to probe allegations of politicization raised by Ziegler and Shapley, as well as findings related to the Biden family's business dealings from Comer's investigation.

The House Judiciary Committee Chairman Jim Jordan and Ways & Means Committee Chairman Jason Smith initiated an impeachment inquiry against President Biden to investigate whether he played a role in his son's business dealings. Despite Biden's repeated denials, evidence suggests that he was present at meetings and engaged in phone conversations with his son and foreign business partners.

In August, a 292-page report was released by House lawmakers, accusing Biden of "impeachable conduct." The report stated that he had "abused his office" and "defrauded the United States to enrich his family."

According to Republicans, there is "substantial proof" that Biden was involved in a "scheme to exploit his position of public trust for personal gain." They claimed that the Biden family and their business partners had received significant sums of money from foreign entities by "falsely suggesting that these payments would grant them access to and influence with President Biden."

In a stunning reversal, Hunter Biden pleaded not guilty and sat for a trial this year after his plea deal for federal gun charges collapsed in the summer of 2023.

Before his trial for federal tax crimes, Hunter Biden pleaded guilty.

After months of pledging not to pardon his son, President Biden ultimately granted clemency.

On Sunday, the president declared a pardon for any offenses against the U.S. that Hunter Biden may have committed from Jan. 1, 2014, to Dec. 1, 2024.

"Since taking office, I pledged not to interfere with the Justice Department's decision-making, and I have remained true to my word despite witnessing my son being unfairly prosecuted," Biden stated. "Despite my son's five and a half years of sobriety, he has faced relentless attacks and selective prosecution. In an attempt to break Hunter, they have also tried to break me. There is no reason to believe this will stop now. It is time for enough."

Biden stated, 'I hope Americans will comprehend why a father and a president would make this choice.'
