Former President George H.W. Bush and his wife, Barbara, are receiving well wishes from around the world as they remain hospitalized in Houston.

The 41st president is in intensive care at Houston Methodist Hospital for pneumonia and the former first lady was admitted to the hospital Wednesday after experiencing fatigue and coughing.

Former President Bill Clinton wrote on Twitter: "41 and Barbara — thinking about you both and sending wishes for a speedy recovery. Love, 42."

Both President-elect Donald Trump and President Barack Obama sent their well wishes to the Bushes as well. Trump said on Twitter that he is looking forward to the couple's quick recovery, while Obama said at a press conference Wednesday that the Bushes "are as fine a couple as we know."
