Billionaire Jeff Bezos expressed optimism about his space company Blue Origin's future with the incoming Trump administration, stating he is not worried about Elon Musk's impact on the president-elect's space plans.

Jeff Bezos in an interview with Reuters said on Sunday he feels "very optimistic" about his space company's future under Donald Trump's incoming administration, and that he is not concerned about SpaceX CEO Elon Musk's influence on the president-elect's space agenda.
