Donald Trump's former primary opponent Sen. Marco Rubio is meeting with the Senate Foreign Relations Committee Wednesday as the president-elect's secretary of state nominee.

Marco Rubio, President-elect Donald Trump's choice to be secretary of state, said Wednesday that the next US administration would seek "bold diplomacy" with a goal of ending Russia's invasion of Ukraine.

Marco Rubio drew bipartisan support among Senate Foreign Relations Committee members at Wednesday's hearing and appears headed for confirmation under President-elect Donald Trump's administration.

Secretary of State nominee Marco Rubio drew bipartisan support ... However, she questioned him on U.S. alliances with NATO and Ukraine. While Rubio said he would follow Trump's directives ...

Among President-elect Donald Trump's Cabinet picks, secretary of state nominee Marco Rubio may face the easiest confirmation process.

The Senator is expected to be an easy confirmation, but that didn't mean there was no drama Wednesday morning.

Rubio is seen as a steady foreign policy hand who has the confidence of Trump and Senate colleagues from both parties.

Mr. Rubio expressed views aligned with those of most senators who work on foreign policy, while taking care not to break from Donald J. Trump’s unorthodox ideas.

During his secretary of state confirmation hearing, Sen. Marco Rubio, R-Fla., said there "will have to be concessions made" by both Russia and Ukraine to end the ongoing conflict between the countries.

Rubio is expected to face questions about the incoming administration’s approach to an historic wave of migration throughout the hemisphere that has dominated U.S. relations with other countries.
