House Minority Leader Nancy Pelosi, D-Calif., said President Trump's tweets Thursday morning are "heartbreaking" because they suggest he may pull resources out of Puerto Rico as they continue to recover from damage left by Hurricane Maria.

In three tweets, the president argued that the situation in Puerto Rico was a disaster "of their own making" and said that they cannot keep Federal Emergency Management Agency, the military, and first responders in the territory "forever."

"The president's tweet this morning ... is heartbreaking," Pelosi said. "It's heartbreaking and it lacks knowledge, knowledge about what the role is of FEMA and the others in time of a natural disaster, what our responsibility is as the federal government to the people of our country, and I remind that the people of the Virgin Islands and Puerto Rico are American citizens."

"We owe them what they need. It's not about a clock. It's about what they need," Pelosi said.

The president started off the tweets quoting Sinclair Broadcasting reporter Sharyl Attkisson and argued that the infrastructure and electric situation in Puerto Rico was a "disaster" before the hurricane.

"'Puerto Rico survived the Hurricanes, now a financial crisis looms largely of their own making' says Sharyl Attkisson. A total lack of... accountability say the Governor," Trump said.

"Electric and all infrastructure was disaster before hurricanes. Congress to decide how much to spend," Trump continued. We cannot keep FEMA, the Military & the First Responders, who have been amazing (under the most difficult circumstances) in P.R. forever!"
