Marco Rubio trying to ‘lift his profile’ by doing more for the Republican Party

Former Australian ambassador to the United States Arthur Sinodinos says US Secretary of State Marco Rubio seems to be doing “more and more” for the Republican Party.

Mr Sinodinos told Sky News Australia that Marco Rubio is trying to “lift his profile”.

“Rubio is a candidate that potentially could appeal to more independents and some crossover voters.”
