July FBI raid on the Virginia home of President Donald Trump's former campaign manager, confirmed on Aug. 9, showed that a federal investigation of possible ties between Trump's campaign and Russian meddling in the 2016 U.S. election was intensifying.

Federal Bureau of Investigation agents executed a search warrant at one of Paul Manafort's homes, his spokesman Jason Maloni said.

U.S. Secretary of State Rex Tillerson said on Aug. 7 that he had told his Russian counterpart that Moscow's meddling in the U.S. presidential election had created "serious mistrust" between the two countries.

Donald Trump described Russian interference in the 2016 presidential election as a "total fabrication" on Aug. 3 amid reports that a special prosecutor has impaneled a grand jury to investigate the issue -- a step toward possible criminal indictments.

"We didn't win because of Russia. We won because of you," Trump said at a campaign-style rally in West Virginia.

Republicans on the House Judiciary Committee are swiftly moving forward with calls to set up a special counsel to investigate the 2016 election, but focus exclusively on the actions of officials in the Barack Obama administration — including Attorney General Loretta Lynch — and Democratic candidate Hillary Clinton.

U.S. President Donald Trump's growing anxiety about the federal Russia probe has spilled into public view with his warning that special counsel Robert Mueller would be out of bounds if he dug into the Trump family's finances. But that's a line that Mueller seems sure to cross.

The American political scene will soon resemble the hit television series "House of Cards," as revelations of contacts and deals between Donald Trump's election campaign and others keep coming in.

President Donald Trump has responded angrily to reports that he is under criminal investigation, deriding a "witch hunt" against him led by some "very bad" people.

The special counsel appointed to investigate Russian influence in the 2016 presidential campaign is now examining whether President Donald Trump tried to obstruct justice, The Washington Post reported late on June 14.

Accusations of obstruction arose last month when Trump fired FBI Director James Comey.

U.S. President Donald Trump is being investigated by special counsel Robert Mueller for possible obstruction of justice, The Washington Post reported on Wednesday, citing unidentified officials, Voice of America reported.

The activities of President Donald Trump's son-in-law and senior aide Jared Kushner have come under FBI scrutiny as part of the probe of Russian interference in last year's presidential election, U.S. media reported on May 25.
