President Trump officially began his campaign for re-election on Tuesday at a rally in Orlando, Fla., touching on themes and promoting accomplishments that are likely to be staples of his appearances from now until Election Day. Here’s a fact-check of his remarks.

Russia

“Nobody’s been tougher on Russia than Donald Trump.”

This is misleading.

Whether Mr. Trump has been “tougher” than any other president is subjective. But it’s worth noting that observers of American relations with Russia point to a disconnect between aggressive policies enacted by the Trump administration and not-so-tough language from Mr. Trump himself.

In his resignation letter in December, Defense Secretary Jim Mattis emphasized that his views on “treating allies with respect and also being cleareyed about both malign actors and strategic competitors” — Russia, for example — were not shared by Mr. Trump.

The Trump administration has indeed imposed sanctions, ordered a missile attack on Syria despite Moscow’s opposition and approved arms sales to Ukraine — actions that could be called “tough.”
