The final day of voting in this year’s midterm elections arrived Tuesday against a backdrop of uncertainty after a year in which President Donald Trump has tried to interfere in how states run their elections and sown doubts about the outcome should Republicans lose.

The Trump administration on Tuesday said it was deferring more than $1 billion in Medicaid payments to California and Minnesota because of “suspected fraud and noncompliance,”

State leaders, including Oregon Secretary of State Tobias Read, say they plan to challenge the order.
