Republicans and Democrats rushed this week to reframe the storylines surrounding an investigation into whether President Trump’s campaign colluded with Russia to interfere in the election following the discovery on Tuesday that Democrats had commissioned a document at the center of the allegations.

Republicans pointed to the revelation as evidence that Trump’s foes manufactured the Russia controversy in order to undermine his candidacy and, ultimately, his presidency. Democrats described the revelation as an unsurprising disclosure about routine opposition research that should not change the focus of investigators digging into Russian collusion.
