Top politicians are paying tribute to Bob Dole following his death on Sunday. He was 98.
Shortly after news of the late Senator's death was made public, President Joe Biden expressed his condolences in a social media statement.
"Bob Dole was a man to be admired by Americans. He had an unerring sense of integrity and honor," Biden, 79, tweeted. "May God bless him, and may our nation draw upon his legacy of decency, dignity, good humor, and patriotism for all time."
In another statement, Biden remembered his close friend and detailed a visit he made to the late politician a month after he was sworn in as president earlier this year.
"Bob had recently been diagnosed with lung cancer, and I was were there to offer the same support, love, and encouragement that they showed me and Jill when our son Beau battled cancer, and that the Doles have shown us over the half century we've been friends," he wrote.

Noting that the two "picked up right where we left off," Biden continued that though they "often disagreed" on certain topics, Dole "never hesitated to work with me or other Democrats when it mattered most."
"Bob was an American statesman like few in our history. A war hero and among the greatest of the Greatest Generation. And to me, he was also a friend whom I could look to for trusted guidance, or a humorous line at just the right moment to settle frayed nerves. I will miss my friend," he added. "But I am grateful for the times we shared, and for the friendship Jill and I and our family have built with Liddy and the entire Dole family."

In a statement of his own, former president Barack Obama expressed condolences from himself and his wife, Michelle Obama. "Senator Dole and I differed on policy, and I didn't serve with him in the Senate. But I did get to know him over the years, and for that I will always be grateful," he wrote.
"Senator Dole was a war hero, a political leader, and a statesman – with a career and demeanor harkening back to a day when members of the Greatest Generation abided by a certain code, putting country over party," Obama, 60, continued, also noting that "his sharp wit was matched only by his integrity, and he lived his life in a way that made it clear just how proud he was to be an American, and how committed he was to making this country everything he knew it could be."

George W. Bush also penned his own remembrance to Dole, who previously served as the longtime leader of Senate Republicans.
"Laura and I are saddened by the passing of a great patriot, Senator Bob Dole," he shared. "This good man represented the finest of American values. He defended them in uniform during World War II. He advanced them in the United States Senate. And he lived them out as a father, husband, and friend."
"Our entire family benefitted from that friendship, including my father," Bush, 75, added. "I will always remember Bob's salute to my late dad at the Capitol, and now we Bushes salute Bob and give thanks for his life of principled service. Laura and I send our heartfelt condolences to Elizabeth and join our fellow citizens in prayer for her comfort."
