President Barack Obama said he has not met his Republican opponent Governor Mitt Romney since last week's election, but that he hopes to do so by the end of the year.
We haven't scheduled something yet. I hope it's before the end of the year, though, that we have a chance to sit down and talk
– Former US Secretary of State Condoleezza Rice
Americans can take pride in last night's peaceful exercise of our democratic right to choose those who will lead us. We are one country, united in our beliefs and our values.
Let us pray for wisdom and courage for our President and all who were elected to office last night. God Bless America.

This was the Republicans election to win. @mittromney is a good man but he just never connected with the people.

I am immensely proud of the campaign we ran, and I remain grateful to Governor Romney for the honour of being his running mate.
I look forward to spending some time with my family in the coming days and then continuing my responsibilities as chairman of the House Budget Committee and representative of Wisconsin's First Congressional District.

I would like to extend my congratulations and good wishes to President Obama on his re-election. I have enormous respect for the President and have always valued our meetings and discussions, particularly on finding a pathway to peace in the Middle East.
I look forward to continuing to work with the President and other world leaders towards real progress in this region in the months and years to come. This issue remains as urgent as ever.
