Investigate the use of taxpayer dollars by the Obama administration for campaigning for Hillary Clinton

President Obama has taken the unprecedented step in actively campaigning for a possible successor. Most presidents just endorse the candidate from their party, and continue to run the government while the election happens. President Obama has used Air Force One, which is taxpayer funded, to fly to events and campaign for Hillary all around the country. While the DNC pays for some of the expenses for these flights the taxpayers are paying for the majority of expenses. These tax dollars should be used to continue to run the government not campaign for a presidential candidate.
