Her rebaptism caused protests from EpiscopalIan leaders, which made headlines as Roman Catholic teaching does not require a second baptism of converts Christians baptized using the Trinitarian formula and water.

Johnson heard of the assassination while attending a Spanish class at the National Cathedral School.

She was unaware whether her father had been injured as well but realized he had been sworn in as the 36th President of the United States when Secret Service agents showed up on her school campus a few hours later.

[4] In 1966, she learned to cook from Zephyr Wright, the White House chef for the Johnson family.

The wedding was broadcast on television (drawing 55 million viewers) and was featured on the August 19, 1966, cover of Life magazine.

[9] In April 2010, Johnson was diagnosed with Guillain–Barré syndrome (also known as Landry's paralysis), an autoimmune disorder affecting the peripheral nervous system.
