President Obama heads to England, as Israeli PM Netanyahu speaks to Congress on peace.
Volcanic ash forced an early arrival in London.
Today President Obama dines with Queen Elizabeth and meets a key opposition leader after wowing crowds and urging peace in Ireland.
"To those who've been willing to take those risks, we are grateful to them," said President Obama.
But it's peace in the Middle East at issue on Capitol Hill today. Israeli Prime Minister Benjamin Netanyahu will tell Congress how he thinks Israel and Palestinians can co-exist.
At a speech before a key Israeli lobbying group Monday, he rejected President Obama's call to begin with borders from four decades ago.
"Israel cannot return to the indefensible 1967 lines," said Netanyahu.
Democrats and Republicans are reassuring Netanyahu that the U.S. supports Israel's security and frowns on Palestinians' ties to terrorist groups.
House Speaker John Boehner said, "When it embraces terrorist organizations, I think it makes its intentions known."
Senate Majority Leader Harry Reid said, "The United States of America will not give money to terrorists bent on the destruction of the state of Israel.”
Peace through diplomacy, at home and abroad is the goal.
