Question: Clark Clifford was an American lawyer who served as political adviser to which president known for launching the Marshall Plan?
Context: Harry S. Truman (May 8, 1884December 26, 1972) was the 33rd President of the United States (1945–53), assuming that office upon the death of Franklin D. Roosevelt during the waning months of World War II.  He is known for launching the Marshall Plan to rebuild the economy of Western Europe, for leading the Cold War against Soviet and Chinese communism by establishing the Truman Doctrine and NATO, and for intervening in the Korean War.  In domestic affairs, he was a moderate Democrat whose liberal proposals were a continuation of Franklin Roosevelt's New Deal, but the conservative-dominated Congress blocked most of them.  He used the veto power 180 times, more than any president since then, and saw 12 overridden by Congress; only Grover Cleveland and Franklin D. Roosevelt used the veto so often, and only Gerald Ford and Andrew Johnson saw so many veto overrides.  He is also the only world leader to have ever used nuclear weapons in war, desegregated the U.S. Armed Forces, supported a newly independent Israel, and was a founder of the United Nations. Lynn Garrison (born April 1, 1937) is a Canadian pilot and political adviser.  He was a Royal Canadian Air Force fighter pilot in the 403 City of Calgary Squadron, before holding jobs as a commercial pilot, film producer, director and mercenary.  Later he became a political adviser in Haiti, and is now an author.  With regard to flying, Garrison is known for his oft-repeated comment, "If it has fuel and noise, I can fly it." The Molotov Plan was the system created by the Soviet Union in 1947 in order to provide aid to rebuild the countries in Eastern Europe that were politically and economically aligned to the Soviet Union.  It can be seen to be the USSR's version of the Marshall Plan, which for political reasons the Eastern European countries would not be able to join without leaving the Soviet sphere of influence.  Soviet foreign minister Vyacheslav Molotov rejected the Marshall Plan (1947), proposing the Molotov Plan the Soviet-sponsored economic grouping which was eventually expanded to become the COMECON.  The Molotov plan was symbolic of the Soviet Union's refusal to accept aid from the Marshall Plan, or allow any of their satellite states to do so, because of their belief that the Plan was an attempt to weaken Soviet interest in their satellite states, through the conditions imposed, and by making beneficiary countries economically dependent on the United States. The Judson Welliver Society is a bipartisan social club composed exclusively of former presidential speechwriters in the United States.  The group is named after Judson C. Welliver, the "literary clerk" to President Warren Harding, usually credited as being the first presidential speechwriter.  Group meetings are usually held after major presidential speeches, such as the State of the Union.  Active members have included William Safire (a Nixon writer who often hosted meetings), Jack Valenti who was a veteran of the Johnson administration, Pat Buchanan (Nixon and Reagan), David Gergen (Nixon, Ford, Reagan, and Clinton), Tony Snow (speechwriter for George H. W. Bush and press secretary for George W. Bush), Michael Waldman (Clinton), George Stephanopoulos (Clinton), James Fallows (Carter), Chris Matthews (Carter), Hendrik Hertzberg (Carter), Anthony R. Dolan (Reagan), Michael Gerson (George W. Bush), and Clark Clifford, who wrote speeches for Harry Truman. George Catlett Marshall, who was Army Chief of Staff, special envoy to China, Secretary of State, President of the Red Cross, Secretary of Defense, and namesake of the Marshall Plan, and his wife Katherine Marshall purchased the property for $16,000 in 1941 and lived there until his death on October 16, 1959.  Legend has it that Katherine paid the owners $10 earnest money and threw the "for sale" sign into the bushes as she left to discourage the competition.  Except for a winter home in Pinehurst, N.C., this house was the only home Marshall ever owned, and was the backdrop to quiet conversations and contemplations of international importance.  Katherine gave the house and 3.88 acres to her daughter, Molly Winn, in 1960 while she moved to Pinehurst for permanent residence.  When Mrs. Winn expressed her desire to sell the property in the early 1990s, several prominent Leesburg citizens under the leadership of B. Powell Harrison were concerned that the property might fall into commercial hands and be demolished and urged the Town of Leesburg to purchase it.  That proved to be impossible, so the citizens formed the George C. Marshall Home Preservation Fund, later the George C. Marshall International Center, and purchased the Marshall House for $2.3 million.  After renovations costing more than $4.5 million, the house opened as a museum on Veterans Day in 2005.  Much of the money for the purchase and renovation was donated by European nations that had benefited from the Marshall Plan.  Further funding was provided by grants from the Commonwealth of Virginia, National Park Service (Save America’s Treasures program), U.S. Department of Housing and Urban Development, Garden Club of Virginia, and generous private donations. The Marshall Plan (officially the European Recovery Program, ERP) was an American initiative to aid Western Europe, in which the United States gave over $13 billion (approximately $132 billion in current dollar value as of September 2017) in economic support to help rebuild Western European economies after the end of World War II.  The plan was in operation for four years beginning on April 8, 1948.  The goals of the United States were to rebuild war-devastated regions, remove trade barriers, modernize industry, make Europe prosperous once more, and prevent the spread of communism.  The Marshall Plan required a lessening of interstate barriers, a dropping of many regulations, and encouraged an increase in productivity, labour union membership, as well as the adoption of modern business procedures.
