Sen. Kamala Harris (D-Calif.) has selected Baltimore as the base for a potential 2020 presidential campaign, according to the Baltimore Sun.

Baltimore, though a long way from Harris’s home state, comes with some advantages for the potential candidate. The city is close to the senator’s office in Washington and has a diverse population.

Harris has yet to announce whether she will seek the Democratic nomination in 2020, though she is widely expected to make a decision soon.

{mosads}A spokesperson for Harris did not immediately respond to The Hill’s attempts to confirm the move.

If Harris decides to run, she will join what is expected to be a crowded Democratic primary field. Roughly half a dozen candidates already have entered the race and several more are expected to do so in the coming weeks.

Among those who have already jumped in are Sen. Elizabeth Warren (D-Mass.), Sen. Kirsten Gillibrand (D-N.Y.) and former Housing and Urban Development Secretary Julián Castro.

Other Democrats, including former Vice President Joe Biden and Sen. Bernie Sanders (I-Vt.), are also reportedly weighing presidential bids and are expected to announce their decisions soon.

Harris, a former California attorney general, was first elected to the Senate in 2016. Since then, speculation of presidential ambitions has swirled. She said last month that she planned to make a decision on a White House run over the holidays.
