U.S. Senator Mitt Romney will vote to allow a subpoena in a Senate Republican investigation of Democratic presidential candidate Joe Biden’s businessman son, Hunter Biden, his office said on Friday. A day after Romney told reporters that the probe appeared to be political, a spokeswoman said the Utah Republican decided to back the subpoena after being assured that the records and witness interview sought would not create a public spectacle. President Donald Trump, without evidence, has attacked as corrupt Hunter Biden’s role as a board director for a Ukrainian gas company while his father was the U.S. vice president.
