“Manafort has nothing to do with our campaign.”

Mr. Manafort was the Trump campaign chairman during the last stretch of the Republican primary campaign. He worked for the campaign for 144 days — not 49 days or three and a half months, as Mr. Trump alternately has claimed.

“Now there has been collusion between Hillary Clinton, the D.N.C., and the Russians.”

The Washington Post first reported in October that the Democratic National Committee and Hillary Clinton’s presidential campaign paid for opposition research that led to a dossier about Mr. Trump compiled by Christopher Steele, a former British spy. Mr. Trump has repeatedly accused Democrats of “colluding” with Russia. But it was a conservative website, The Washington Free Beacon, that first paid a research firm for the opposition research. It stopped when Mr. Trump won the nomination. The firm, Fusion GPS, was then paid by the Democrats for the research that became the dossier.

This is misleading.

Collusion, which is generally understood as secretive and often illicit collaboration, has no defined legal meaning. Mr. Steele did use Russian sources to compile his dossier, and reported his findings to the F.B.I. But there is no evidence anyone from the Clinton campaign met with Russian officials directly and conspired to manipulate the American election.

“Nobody asks John Podesta about the company that he has with his brother in Russia.”

As evidence of Democratic collusion, Mr. Trump has said John D. Podesta, Hillary Clinton’s campaign manager, owned a company in Russia.

False.

Mr. Podesta does not own a company in Russia. The consulting firm that he and his brother, Tony Podesta, co-founded is based in Washington, not Russia. (The firm did, however, lobby on behalf of a Russian bank.)

“We had Hillary Clinton give Russia 20 percent of the uranium in our country.”

Mr. Trump has accused Mrs. Clinton of selling American uranium to Russia at least 16 other times, sometimes briefly referring to the issue simply as “Uranium One.”

This is misleading.

Uranium One is a uranium production company with holdings in the United States. Mrs. Clinton was secretary of state when the Obama administration allowed Russia’s nuclear agency to purchase the company. The State Department was one of nine agencies — as well as federal nuclear regulator and a state regulator — that had to sign off on the sale. There is no evidence that Mrs. Clinton was personally involved.
