Maybe US is doomed? After former US President Donald Trump being impeached.

Now US House Speaker Kevin McCarthy has announced he is launching an impeachment inquiry against President Joe Biden, yielding to mounting pressure from former President Donald Trump and his allies.

Republicans have been investigating the president since they took control of the House in January.

The hearings have found no concrete evidence of misconduct by Mr Biden.

With this impeachment inquiry Trump hopes to avenge his 2020 election loss to Biden and win back the White House.

They have tried to, shed more light on business dealings by the president Biden's son Hunter Biden - which Republicans say are questionable - and on Mr Biden's knowledge of his son's activities.

In a brief statement at the US Capitol, Mr McCarthy said there were "serious and credible" allegations involving the president's conduct.

"Taken together, these allegations paint a picture of a culture of corruption," he said.

The White House was quick to condemn Mr McCarthy's decision.

Hunter Biden is currently under federal investigation for possible tax crimes related to his foreign business interests.

Mr McCarthy, a California lawmaker, also alleged that the president's family has received special treatment from Biden administration officials investigating allegations of misconduct.

The White House has denied any involvement in the Hunter Biden case, and said that President Biden has no ties to his son's business operations.

Biden previously had mocked Republicans over a possible impeachment and the White House said they have no basis to do so.

This inquiry will give congressional investigators greater legal authority to investigate the president, including by issuing subpoenas for documents and testimony that can be more easily enforced in court.

The US constitution states a president can be impeached for "treason, bribery, or other high crimes or misdemeanours", a process which can end in them being removed from office.

However, any effort to remove President Biden would be unlikely to succeed.
