March 15 (Reuters) - Highlights of the day for U.S. President Donald Trump's administration on Wednesday: RUSSIA A key Republican lawmaker says he does not believe the Obama administration wiretapped Trump Tower during the 2016 election campaign, adding to pressure on FBI Director James Comey to provide evidence supporting or debunking Trump's claim.
