Donald Trump's search for a vice presidential running mate is intensifying as he awaits sentencing for felony convictions. Prospective VP candidates have recently received vetting materials to submit as the selection process narrows. The top contenders are said to include North Dakota Governor Doug Burgum, Senators Marco Rubio, Tim Scott, and JD Vance. Burgum has spent more time recently with Trump and is among those who received a vetting request. Trump's decision may not come until closer to the July Republican convention.
