U.S. President Barack Obama says there is never a substitute for the love and support of a parent in a child's life.
In his weekly address Saturday, Obama paid tribute to the country's Father's Day observance by saying the most important job many American men will ever have is "being a dad."
The president said he wished he had a father who was around to help teach him "values like hard work," integrity and responsibility. He added that good parents must make frequent sacrifices and show "unconditional love" to help their kids grow into the people they were meant to be.
Americans will celebrate Father's Day Sunday.
In the weekly Republican address, U.S. Senator Lamar Alexander of Tennessee called for "a permanent solution to all student loan interest rates" before some automatically rise on July 1st.
Alexander, a former U.S. secretary of education, said "It's fairer to students and fairer to taxpayers" to allow the market to set interest rates, and that all student borrowers can benefit from the current low rates.
