President Donald Trump's pick to succeed Rick Perry as energy secretary won easy Senate confirmation Monday, despite a Democratic senator's objections that the nominee hadn't fully answered questions related to the Trump impeachment investigation.
Several other Democrats joined Republicans in approving Deputy Energy Secretary Dan Brouillette's promotion, 70-15.
A House impeachment panel is scrutinizing Trump's push for Ukraine to investigate a company employing a son of rival Joe Biden.
He told a Senate committee hearing last month he knew nothing about any of the Ukraine conversations under scrutiny.
Republican senators in Brouillette's committee confirmation hearing made clear they expected him to keep using the agency to advocate for U.S. fossil fuels, although Brouillette's first remarks at the hearing stressed the department's research on supercomputers and other scientific efforts.
