Former U.S. Attorney General Eric Holder is again considering running for the Democrat nomination for president in 2020 after previously ruling out a run, a move that comes as former New York City mayor Michael Bloomberg has filed presidential primary paperwork in Alabama signaling he may be a late entrant to the race. All of this comes as speculation builds that former Secretary of State Hillary Rodham Clinton, the failed 2016 Democrat presidential nominee, may run again in 2020 as well.
