More than $749 million of Guam buildup funding would be diverted for a border wall as a result of President Trump's emergency declaration, according to an announcement by Guam Del. Michael San Nicolas.

The amount represents more than 10 percent of the U.S. commitment to the realignment, San Nicolas said. About $3.6 billion in defense funds would be used for the border wall.

"Diversion of these funds will certainly set back the military buildup once again, and could further jeopardize it altogether as it represents a softening of the commitment," San Nicolas said.

San Nicolas said he would co-sponsor a resolution challenging President Trump's emergency declaration if he should execute one.

"We can not allow the real threat of fueling China assertiveness to get walled in," San Nicolas said.

He said he would also ask Gov. Lou Leo Guerrero to request that Trump exclude Guam projects from emergency fund diversion. The governor is in Washington, D.C., meeting with Trump and his cabinet members this week.
