The statement reports that Jorge Elorza said Congress has the ability to bring hope back to DREAMers and urged bipartisan cooperation. As a matter of factual reporting of what someone said, this is a verifiable statement about Elorza's words. The content of what he said — that Congress has the ability to act on behalf of DREAMers and that he urged bipartisan action — is a statement of opinion/policy preference, not a factual claim that can be true or false. However, as a report of what he said, it is accurate and thus TRUE.

Congress possesses the constitutional authority to pass immigration legislation, such as the DREAM Act, which could provide relief to DREAMers, thus it factually has the ability to bring hope back to them.

Congress indeed has the legislative power to affect DREAMers' status (e.g., through DACA or immigration reform), and the quote accurately reflects Elorza's expressed opinion.

Congress does have the constitutional authority to pass legislation that could address the status of DREAMers, making the factual claim about their ability accurate.
