Sen. Joni Ernst (R-Iowa) said on CNN's "State of the Union" Sunday that President Trump's Senate impeachment trial has helped bring to light information about Joe and Hunter Biden's activities in Ukraine and that this could influence how Democrats vote in the Iowa caucuses on Monday.
Why it matters: Biden seized on similar comments Ernst made to reporters last week, claiming that she "spilled the beans" by admitting that Trump's lawyers were using the impeachment trial to "smear" him. Democrats have also alleged that Trump's attempts to pressure Ukraine to investigate the Bidens were intended to help his election prospects, which Republicans have largely denied.
